It is important that you understand what exactly plastic molding is, and how it can benefit your business, plastic moulding is the process of using a plastic molding machine and plastic mold to create plastic products. Essentially, the plastics material goes into the heating barrel, the heating barrel has a temperature up to 280-320 degrees to melt the plastic material into a liquid, which then mixes and is forced into a mould cavity. Then cooling the mold and get the plastic sharp what you want, It is used for some of the small or big components which you want have in your ending products,
Plastic molding parts could be a part of your new model, if you are doing new product development, then you will need plastic molded parts in your whole business.
If you need specific parts for your business, first you need to find a plastic mold maker and plastic moulding company. And we are the one that could solve your issue on plastic molds & molded parts.
There are several types of plastic molding processes as below, to understand this maybe help you to develop your project and find the best process to make the best result.
Automotive injection mold, plastic mold
The most common and faster molding manufacturing processing method for forming thermoplastics is an injection molding process, which involves forcing molten plastic into injection mold at high pressure. The plastics then form to the shape of the mold as it cools and solidifies. then eject the molded part out from the injection mold and continually repeat this process, injection moulding can produce large quantities of parts, accommodate a wide variety of part sizes, offer excellent part-to-part repeatability, and make parts with relatively tight tolerances. Moulds can produce intricate features and texture surface requirement plastic parts, as well as structural and assembly elements such as ribs and bosses. Undercuts and threads usually require mold mechanisms, of course, more complex part design and size is bigger, then the mold manufacturing cost is muc hhigh accordingly, compare to other molding processes, that mold cost is much higher than others but the unit price is supplier low than others molding process,
The injection molding process generally requires large order quantities to offset high mold costs. for example, a $50,000 mold producing only 1,000 parts would contribute $50 to the cost of each part. The same mold producing 500,000 parts would contribute only $0.10 to part cost. Additionally, mold modifications for product design changes can be very expensive. Very large parts, such as automotive bumpers and fenders, require large and expensive molds and presses. this is one of the best molding processes to produce millions of the same feature molded parts with the best competitive unit price.
Injection moulding is one of our mean business, if you have any project that needs injection molding services, you are welcome to contact us anytime, we guarantee you will be 100% happy with our service, you do not need to believe us, you can check with our current customers, and hearing what they say to us, contact us now.
In extrusion forming, molten material continuously passes through a die that forms a profile that is sized, cooled, and solidified. It produces continuous, straight profiles, which are cut to length. Most commonly used for sheet, film, and pipe production, extrusion also produces profiles used in applications such as road markers, automotive trim, store-shelf price holders, and window frames. Production rates, measured in linear units, such as feet/minute, ordinarily are reasonably high. Typically inexpensive for simple profiles, extrusion dies usually contribute little to the product cost. Part features such as holes or notches require secondary operations that add to the final cost.
Thermoforming creates shapes from a thermoplastic sheet that has been heated to its softening point. Applied vacuum or pressure draws or pushes the softened sheet over an open mold or form where it is then cooled to the conforming shape. The process of stretching the sheet over the form or mold causes thinning of the wall, especially along the sides of deep-drawn features. Mold or form costs for this low-pressure process are much lower than for injection molds of comparable size.
Thermoforming can produce large parts on relatively inexpensive molds and equipment. Because the plastic is purchased as sheet stock, materials tend to be costly. Material selection is limited to extrusion grades. Secondary operations can play a large role in part cost. Thermoformed parts usually need to be trimmed to remove excess sheets at the part periphery. This process cannot produce features that project from the part surface such as ribs and bosses. Cutouts and holes require secondary machining operations.
Blow molding efficiently produces hollow items such as bottles, containers, and light globes. Design permitting, the process may also produce hollow shapes such as automotive air ducts and gas tanks. Wall thickness can vary throughout the part and may change with processing. Blow molding cannot produce features that project from the surface such as ribs and bosses. Part geometry determines mold and equipment costs, which can range as high as those for injection molding.
The two most common types of blow molding are extrusion and injection. In extrusion blow molding, mold halves pinch the end of a hanging extruded tube — called a parison — until it seals. Air pressure applied into the tube expands the tube and forces it against the walls of the hollow mold. The blown shape then cools as a thin-walled hollow shape. A secondary step removes the vestige at the pinch-off area.
Injection blow molding substitutes a molded shape in place of the extruded parison. Air pressure applied from inside the still-soft molded shape expands the shape into the form of the hollow mold. This process eliminates pinch-off vestige and facilitates molded features on the open end such as screw threads for lids.
In rotomolding, a measured quantity of thermoplastic resin, usually powdered, is placed inside a mold, which is then externally heated. As the mold rotates on two perpendicular axes, the resin coats the heated mold surface. This continues until all the plastic melts to form the walls of the hollow, molded shape. While still rotating, the mold is cooled to solidify the shape.
This process is used for hollow shapes with large open volumes that promote uniform material distribution, including decorative streetlight globes or hollow yard toys. Mold and equipment costs are typically low, and the process is suited to low-production quantities and large parts. Cycle times run very long. Large production runs may require multiple sets of mold,
