INJECTION MOLDING
Rapid 3D-printing proofing, modeling, mass production and assembly in one stop
What is Injection Molding
Plastic injection molding is the process by which granular raw materials (plastic granules) are heated down into a molten state and then advanced through a screw in an injection molding machine, known as a reciprocal screw, before being injected into a sealed mold. Once inside, the now-molten raw material flows to all the mold’s corners before cooling down and assuming the shape of the desired product. Typically, 3D printing is used early on in this process to reduce the risk of the mold altering by testing and verifying assembly and design.
The injection process typically involves the following five stages:
-
Mold clamping: The mold is closed and sealed.
-
Injection: The molten plastic material is injected into the sealed mold.
-
Pack press: Maintained pressure within the mold prevents the plastic from shrinking and thus failing to take the shape of the mold after it has cooled.
-
Cooling: This process allows the plastic to be removed from the mold after dropping to a certain temperature.
Ejection: The mold is opened, and an ejector pin structure is used to remove the product.
At HUBTICLE, our experience has taught us to divide injection molding products into the following categories:
Plastic: The injection molding process temperature and length of each stage of the process vary according to the types of plastic materials being used. Common plastic-material products include 3C products and plastic shells for household appliances, plastic grips, and car bumpers. For plastic materials, we typically use ABS, PA, PP, PE, and POM. We also use Elastomer materials, such as TPA, TPR, and TPU, to satisfy customer requirements.
Rubber and Silicone: The injection molding of rubber and silicone differs from traditional solid rubber molding methods in that these materials can replace previous extrusion molding methods and produce more diverse appearances for products. Common products containing silicone include milk bottles, straps, cell phone sets, earphones, earplugs, oil seal rings (O-rings), conductive rubber, and more.
Bakelite (phenolic): Bakelite is a non-absorbent, non-conducive (insulated or non-conductive), high-strength, and high-temperature resistant synthetic chemical substance used almost exclusively for electrical appliances, including electrical insulating plates, switches, sockets, and circuit boards, among others.
