Insert Molding (Moulding), Plastic Injection Molding

SINCERE TECH offers Insert Molding Services as an add-on to the plastic injection molding service.  There is one direct difference between the two processes; the plastic injection molding process only uses plastic material in order to create a product.  On the other hand, the Insert Molding process includes other types of plastic and/or metals in order to create a more advanced product. There are thousands of uses for Insert Molding manufacturing.

The Insert Molding Process

The Insert Molding process starts off by either inserting the metal inserts before the custom injection molding process, or they can be inserted during the custom injection molding process.  If the inserts are chosen to be inserted during the plastic injection molding process, an Insert Moulding process operator or a robotic arm will load them.  If chosen to insert the metal inserts after the plastic injection molding operation, the same robotic arm or Insert Molding process operator will load them after the plastic injection molding process is complete. Usually, Insert Molding takes place after the custom injection molding process. This procedure ideally reduces insertion costs, which can save our customers substantial costs on custom insert molding projects. If you want to know more knowledge about insert molding, please go to what is insert molding page to take a look.

Regarding the Insert Molding process, there can be some very nice advantages when a robotic arm is handling parts.  When it comes to removing the molded parts and getting them ready for more processes, a multiple-axis robot can do that faster and more accurate than a human.  After the molded part is created and removed from the mold, the robot grips the part and moves it to either a location to be held or onto a system to be inspected.  The manufacturing equipment’s general layout and the kind of product being created are the determining factors in making this choice.

In order to assure a high level of quality for many parts that go through Insert Molding, robots can have vision systems mounted on them.  These vision systems inspect parts faster than a human, as well as know exactly what the metal component’s placement accuracy is.

Several industries thrive upon the products created through the Insert Molding process.  Actually, there are so many products created through this type of custom injection molding process, to buy inset molding from injection mold china company, that will save super cost since the low labor cost in China.  Here is a list of the industries these products belong to, and there is a list of the products that are created through this type of custom injection molding:

insert molding

Insert Molding metals and plastics together in a molded part, or multiple metals or materials molded together into a single molding part. we sometimes called metal insert molding or metal screw/brass insert molding, sometimes we call insert molding as over-molding. Insert molding (moulding) can be used in automobile, cooking ware, household equipment, instruments, devices, knobs, electrical components and more industrial, Insert molding is not only reducing assembly and labor costs but also better than assembly part, reduces the size and weight of the part, improves component reliability, and delivers improved part strength and structure with enhanced design flexibility.

Today over 90% of insert molding parts are come from China molding manufacturing, the most important thing is China has low labor cost and high-quality control, and another factor is China can do assembly all of your ending parts together and ship to you, we are professional in plastic mold making and plastic molding manufacturing over 18 years, we have strong engineering, mold maker team, quality control production, we can make your project from start to end, no matter normal molding, 2k injection molding, insert moulding (molding), medical plastic molding, automobile industrial, cosmetic injection molding parts, or home appliances injection molding.

The Process of insert moulding ( molding)

The process is same as injection molding process, and use same injection molding machine to inject molten raw material into a plastic mold – the plastic is then solidified by cooling systems- and then the press opens and the molded parts are ejected, one different is before mold close we need put the metals into the mold and start all of injection molding process as injection molding,

Insert molding uses the same materials as the injection molding process except the metal added into mold before mold close. For intense, the same thermoplastics are used. Same mold steel, same mold structure, same injection molding machine, maybe sometimes need to use vertical injection molding machine for some special case, but all are injection molding machines which are working on thermoplastics

Some injection Molding manufacturers use vertical/vertical injection molding presses that use gravity to help in the insert molding process by maintaining the insert in position during mold closing. Insert in position during mold closing.

Most vertical insert molding machines have a feature that utilizes multiple bottom mould halves to be used with a single cavity half. While one bottom half is molding with the cavity half, the other bottom is available to be loaded together with the metals and other inert molding components.

Since multiple Bottom halves make it possible for inserts to be placed in one bottom half while the other one is in the molding step, cycle time is reduced.

Below are some of the inert molding parts we made before. If you have any project that needs brass insert molding or any metal insert molding, send us your requirement for a quotation.

How the insert molding can improve your molding parts and solve your issues.

Insert molding can be a highly efficient alternative to the assembly of discrete parts using soldering, connectors, fasteners, or adhesives. Its benefits over such methods include:

Insert molding can be an extremely efficient alternative to the assembly of the device, fasteners, connectors, or adhesives. To list all of the advantages there are some benefits for molding part as below:

  1. Reduce molding parts size
    Since molding parts that have a metal insert molded together with plastics, so the part size can be designed smaller compare to assembly parts, and the part weight will be less than the assembly parts, this will reduce the material cost which means save the cost by the better result.
  2. Reduced assembly and labor costs
    Because insert molding made by a single shot but have two or more parts joint together in an ending molding parts, this reduces assembly and labor costs, only need a worker to put the insert part into the mold during the molding production, a single insert or multiple inserts can be molded in one shot, the more complex insert molding part than the more benefits with insert molding
  3. Increased reliability
    Insert molding is molded together by the plastic molding process. So every part tightly molds in thermoplastic, an insert molded component prevents part loosening, mismatch, misalignment, and other problems. The plastic resin provides improved against shock and vibration.
  4. Increased design flexibility
    As a designer should be appreciated that it is a molding process with insert molding. Because we have this insert molding process, the designers will e save time to think about how to assembly the part together. Hot to fasten the metal parts and plastic part tight together. How to save the place for other components, so the process to let them design jobs more efficient.
  5. Save injection molding cost and work more efficient
    When inserts are used during the moulding stage than standard injection molding machines sometimes make it more difficult for operators to put inserts into their correct place in the mold. Like some small metal parts or multiple metal parts or some insert parts are easy to drop done the floor when put the inserts molding into the mold, for this reason, vertical injection machines are most efficient, this will save lots of time and injection molding cost.
