How To Save Injection Molding Cost By Multiple Cavity Mold

When you have a project then you may need plastic injection molded parts, the first thing you need to do is finding a plastic mold company to make mold & molded parts, but before start this I think you need to check injection molding cost and mold cost in advance for investment budget, multi cavity injection molding will be one of the best way to save unit production cost.

Like other things, there is no one solution that suitable for all of projects, below are some suggestions on how to save injection molding cost, there have both advantages and disadvantages, by reading this you could choose the one base on your project requirement.

What is multi cavity injection molding

Multi-cavity injection molding is typically used when high volume production of identical parts is needed. It allows for the efficient production of multiple parts in a single cycle, which can significantly increase production rates and reduce the cost per part. Additionally, using a multi-cavity mold can also help to reduce the overall cost of the mold itself.

Multiple cavity mold means the number of cavities greater than one, which means that has more than one part in an injection mold, It is usually professional to say cavity, One cavity or two cavities, for examples 8 cavities mold means one molding cycle to mold 8 parts with the 99% same part feature, dimension, shape, size, etc.

Some examples of products that may be produced using multi-cavity injection molding include automotive parts, electronic components, toys, and household items. It is also commonly used in the production of medical devices, personal care products and packaging.

When do we need Multiple Cavity Mold?

There are some factors to make decisions before starting to make your plastic mould.
1, the size of the product,
2, the number of the product requirement
3, the size of the machine, if you only buy plastic molded parts then you do not need to care about this point, you plastic molding supplier we check this.

If the size of the product is small, such as the computer keyboard button, usually make 24 or 48 Multiple Cavity Mold, you must say why not make 30 or 40, this is because for the balance mold layout and material filling balance, especially when you use cold runner mold. so normally multi-cavity mold is 4, 8, 16, 24, 48, 96 cavities are better options.

When we make multiple cavity mold and the cavities are more than 24, we normally suggest making hot runner mold, one part per hot-drop, at least to use 6 hot runners to the cold runner, which means four cavities per hot drop. this could save the cycle time and keeping the best quality of injection molding parts.

The advantages of Multiple Cavity Mold

The reason we make multi-cavity mold, the question is simple, we need to save production unit cost for each plastic molded parts, multi-cavity molds have several advantages over single-cavity molds in injection molding:

  1. Increased production efficiency: By producing multiple identical parts in a single cycle, Multiple Cavity Mold can significantly increase production rates and reduce the overall production time.
  2. Reduced cost per part: Multiple Cavity Mold can produce multiple identical parts at a lower cost per part than single-cavity molds.
  3. Reduced tooling costs: Since multi-cavity molds require only one tool, the overall cost of the mold is typically lower than that of multiple single-cavity molds.
  4. Better consistency: By producing multiple identical parts in a single cycle, multi-cavity molds can improve the consistency of the final product, reducing the need for rework or scrap.
  5. Reduced labor costs: Multi-cavity molds require less labor to operate than multiple single-cavity molds, as the operator only needs to monitor one machine.
  6. Reduced material consumption: By producing multiple parts in a single cycle, multi-cavity molds can also reduce the amount of raw material required to produce the final product.
  7. Improve part quality: Due to the consistency in the process and the precision of the machinery, multi-cavity molds can produce parts with tighter tolerances and better surface finish.

The disadvantages of multi cavity mold

We all know that all of the customers prefer the multiple cavity mould since this can save lots of production cost, but there are other factors you need to think about before making decision, because make plastic mold is not cheaper, make multi-cavity mould is more expensive than single cavity mold, some times double or even 3 times expensive than single cavity or two-cavity mold.

For example if you make 24 cavity mold, then you at least us 6 hot runner drops for the mold, the pure hot runner cost is around USD 5400 ( YUDO brand), if use China local brand of hot runner still need USD 3000, and this cost some times is enough to make 2 cavities cold runner mold, since there are many cavities in one mold, the mold manufacturing cost is high than the less cavity mold as well, this is another cost, so total cost is two or three times more is not surprised, below listed some disadvantages while use multi cavity mold:

  1. Higher initial cost: The initial cost of a multi-cavity mold can be higher than that of a single-cavity mold, especially for complex designs.
  2. Greater complexity: Multi-cavity molds are more complex than single-cavity molds and require more precise machining and design. This can lead to longer lead times for tooling and increased risk of defects.
  3. Higher maintenance costs: Due to the complexity of the mold and the increased number of moving parts, multi-cavity molds may require more maintenance and repairs than single-cavity molds.
  4. Greater risk of defects: With multiple cavities, the risk of defects is greater, as a problem in one cavity can affect multiple parts.
  5. Increased cycle time: Multi-cavity molds have longer cycle times than single-cavity molds as the machine has to fill multiple cavities at once.
  6. Greater potential for warpage: Multi-cavity molds have to be designed to account for the potential warpage that can occur during the cooling phase of the injection molding process.
  7. Increased risk of sink marks: As the material cools it will shrink, if the mold design is not optimized for multi-cavity, sink marks may appear on the surface of the parts.
  8. Increased risk of flash: Flash is the excess material that is extruded from the mold. Multi-cavity molds can be more prone to flash than single-cavity molds as the pressure and flow rate of the material is increased to fill multiple cavities.

When do you need multiple cavity mold

There is some simple suggestion when do you need to single cavity mold (may 2cavities at fist), when you should make the multi-cavity mold, like 8 cavity mold, 16 cavity mold or more. When you are sure that you will need the plastic parts more than one million or at least 0.5 million, then go to 8 or more mold cavities will surely save cost for you.

You may need to pay more cost on plastic mold manufacturing, but compare the production cost you are going to save, this injection mold cost is insignificant, because you will save 10 times more than this injection mold cost.

If you are not sure how many plastic moulding parts needed at the first, or this is depending on your business market sell, then we suggest use the 2 cavity mold at first, because this can save the plastic mold cost for you in advance, after you open your market, and the requirement of injection molded parts increased, you still can save injection molding cost by making new multiple cavity mold.

You use the existing mold to produce the parts at the same time and  make new multi-cavity mold, this will not have a delay as well, after the multiple cavity mold finished then you only need to run this multi-cavity mould, but if the quantity requirements are not so high, then you use the currently molds to produce, so you still have good profits with less investment (compare to make multi-cavity mold at first beginning).

When do you need single cavity mold

A single cavity mold is a type of mold used in the injection molding process. It consists of a single cavity or impression that forms the desired shape of the plastic part. This type of mold is used when the production volume is low or when the part design is complex and requires more attention to detail.

Advantages of using a single cavity mold include:

  1. Flexibility: Single cavity molds allow for more flexibility in terms of part design and material selection. Each cavity can be customized to meet specific requirements.
  2. Precision: With only one cavity to focus on, manufacturers can pay more attention to detail and ensure higher precision in the molding process. This is particularly important for intricate or complex part designs.
  3. Cost-effective for low volume production: Single cavity molds are cost-effective for low volume production runs. They have lower initial tooling costs compared to multi-cavity molds and are more suitable when the production quantity is small.
  4. Material compatibility: Single cavity molds are ideal when different materials or processes are required for each part. This allows for the production of diverse parts with varying material properties.

A single cavity mold is typically needed when you require a small quantity of parts or when the part design is complex and requires more time and precision to manufacture. It is also used when the part size is large and cannot be accommodated in a multi-cavity mold. Additionally, a single cavity mold may be preferred when the cost of manufacturing multiple cavities is not justifiable or when the part design requires different materials or processes for each cavity.

How much does Plastic injection moulding cost?

The most commonly asked question in the molding industry is, “How much the plastic injection moulding cost“? Well, the answer to this question largely depends on several factors, especially for the fact that plastic mold production has the highest upfront cost in all of the injection molding types

Plastic Injection Moulding CostTo many who have had the same question and can’t seem to get the right answer, you bumped into the right content. This post will go into the depths explaining the variables determining the cost of plastic injection moulding cost and the price for making the plastic molding parts. By tackling the underlying factors, it will be easy to estimate the expected cost. Let’s get to it!

Number of Cavities and volume of your mold

There is a close correlation between the number of cavities in your mold and their cost. If the mold has a high number of cavities, it means more time is needed for manufacturing it, and additional tooling has to be done. The lower the number of cavities in each mold, the lower the pressing time, and the lower the opening cost of manufacturing for each mold.

Part Design Complexity

For a more intricate part design, the resulting mold will be as complex as the part, and this will increase the plastic mold cost. Choosing a less complex part design could cut on your cost quite significantly. However, it is important to put in mind the factors that determine design complexity. These could include, surface finishing, fine detailing, undercuts to be used, among others. You can always seek expert advice to help you choose a design that won’t eat into your budget unnecessarily.

Resin Choice Consideration

There are a number of variables that will influence the cost of plastic injection molding based on the resin choice you use. Ranging from the quantity, grade, resin availability to whether the resin requires extreme molding temperatures, all these will affect the overall upfront cost. For example, if the resin will be found to have abrasive materials like glass or minerals, the cost of mold maintenance will be affected.

Type of plastic part material

This would seem to be an easy consideration like we are talking of plastic injection molding, so we only need plastic parts so that you may say. But there are innumerable plastic types in the likes of PP, PS, PET, PVC, HDPE, just to mention but a few. Each type comes with different prices depending on the material and part size. For large parts, similar large molds and additional material will be needed, and besides, the time taken for machining will be affected. All these variables will impact the overall quote of plastic injection molding.

What will be the cost of making plastic injection moulding parts?

There are many factors that can effect to the plastic injection moulding cost. These factors include the part features, part weight and part size, the type of plastic resin, the volume of parts being produced each time, and the yearly production volume. Each of these factors can be impact to the plastic injection molding cost, and will effect the injection mold cost as well.

The part geometry is one of the primary factors that can affect the plastic injection moulding cost, because this will increase the initial mold cost. Part with tight tolerances, or complex geometries that require more time and more machining cost to produce, resulting in higher production costs. Additionally, parts that require special features such as undercuts, threads, or inserts will also increase the mold cost of manufacturing.

The size and weight of the part can also impact the plastic injection moulding cost. Larger  size of parts requires more plastic material, longer cycle times and big tonnage of  injection mold machine, which can increase the overall production costs. Additionally, larger part size requires larger mold size, this will increase the mold manufacturing cost as well.

The type of plastic material used  for plastic injection molding parts can also influence the cost of production. Different types of plastics have different costs, with some materials being more expensive than others. Additionally, some special material maybe 5-10 time more cost the normal plastic material, so choose the material is important to save the overall injection molding cost.

The number of parts being produced and the production volume are also important factors to consider when determining the cost of plastic injection molding. Producing a small batch of parts may be more expensive on a per-unit basis than producing a larger volume of parts. Additionally, larger production volumes may allow for economies of scale, resulting in lower production costs per part.

How Much Does Injection Molding Cost?

Injection molding is a widely used manufacturing process that involves injecting molten material into a mold cavity to create complex and precise parts. if you need injection molding parts, it’s crucial to understand the injection molding cost. By gaining insights into the factors that influence injection molding cost and implementing effective cost reduction strategies, businesses can optimize their production and maximize profitability.

Plastic Injection Molding Cost

Plastic Injection Molding Cost

Plastic Injection Molding Cost Guiding Tips

There are meanly four parts of cost: Plastic Material Cost, Molding Production Cost, Plastic Mold Cost, Part Color Cost, let us explain those four mean costs one by one.

Plastic Material Cost

First, the plastic raw material cost will effect the plastic injection molding cost, it is determined by the weight of material that is required and the unit price of that material. The weight of the material is a result of the part volume and material density; however, the part’s maximum wall thickness can also play a role. The weight of material that is required includes the material that fills the channels of the mold.

The size of those channels, and hence the amount of raw material, is largely determined by the thickness of the part, the selection of the material affects the unit part price as well, a different type of plastic material has a different price, for example, PP material is a totally different price than ABS material, so the material cost for plastic part includes two parts, one is the weight of the material, one is the type of material for the plastic part.

Second, the injection molding machine process cost will effect the plastic injection molding cost, it is primarily calculated from the hourly rate and the cycle time. The hourly rate is proportional to the size of the injection moulding machine being used, so it is important to understand how the part design affects machine selection. Injection molding machines are typically referred to by the tonnage of the clamping force they provide.

The required clamping force is determined by the projected area of the part and the pressure with which the material is injected. Therefore, a larger part will require a larger clamping force, and hence a more expensive machine. Also, certain materials that require high injection pressures may require higher tonnage machines. The size of the part must also comply with other machine specifications, such as clamp stroke, platen size, and shot capacity.

Injection Molding Processing cost

The cycle time will effect plastic injection molding cost, cycle time can be broken down into the injection time, cooling time, and resetting time. By reducing any of these times, the production cost will be lowered. The injection time can be decreased by reducing the maximum wall thickness of the part and the part volume. The cooling time is also decreased for lower wall thicknesses, as they require less time to cool all the way through.

Several thermodynamic properties of the material also affect the cooling time. Lastly, the resetting time depends on the machine size and the part size. A larger plastic part will require larger motions from the machine to open, close, and eject the part, and a larger machine requires more time to perform these operations.

Plastic Mold Cost

Third, the plastic mold cost has two main components – the mold base and the machining of the cavities. The cost of the mold base is primarily controlled by the size of the part’s envelope and design feature. A larger plastic part requires a larger mold, more expensive mold base. the complex part design requires complex molds, that will effect the mold cost.

The cost of machining the cavities is affected by nearly every aspect of the part’s geometry, complex mold cavity requirement lots of CNC machining cost and time, that will increase the plastic injection mold cost, on the other hand will increase the plastic injection molding cost as well.

The primary cost driver is the size of the cavity that must be machined, measured by the projected area of the cavity (equal to the projected area of the part and projected holes) and its depth. Any other elements that will require additional machining time will add to the cost, including the feature count, parting surface, side-cores, lifters, unscrewing devices, tolerance, and surface roughness.

The quantity of parts also impacts the plastic injection mold cost. A larger production quantity will require a higher class mold that will not wear as quickly. The stronger mold material results in a higher mold base cost and more machining time.

One final consideration is the number of side-action directions, which can indirectly affect the plastic injection molding cost. The additional cost for side-cores is determined by how many are used. However, the number of directions can restrict the number of cavities that can be included in the mold. For example, the mold for a part that requires three side-action directions can only contain two cavities. There is no direct cost added, but it is possible that the use of more cavities could provide further savings.

Injection molding Color Cost

Forth, the plastic molding color is also cost effect to the plastic injection molding cost, normally does not have too much effect, but this is still depending on which parts color do you require if you need white color for your plastic parts, then the cost will be 10% more than another color, if you require clear color (transparent molding parts) molding parts, then the cost will be 25-40% high than normal color molded parts.

When you need white color injection molding parts, then the molding shop needs to clean the barrel very well, and not allow any other color max in this injection unit and material, this will take time and waste some material, and the other thing is the waste rate will be increased, that is the reason the white color plastic parts is little high than other colors.

When you are looking for transparent injection molding parts like PC injection molding, PMMA molding, or PS molding parts, the molding shop needs use special injection unit to produce this type of molding parts, they need to clear the unit barrel very well and use some good quality injection molding machine to produce the clear plastic molding parts, because any tiny molding defects on the transparent molding parts will be easy to identify.

So you need to make the best quality molding parts, the waste rate is higher, and need to use the high tech injection molding machine, and all of those are more costly than normal molding production.
