Threaded Inserts For Plastic Injection Molding

We offer injection molding inserts as per customer designs and samples.

Threaded inserts for plastic injection molding.

Thru threaded knurled spacers types stka aluminum inserts stkb brass inserts and stkc stainless steel inserts include a uniform knurl diameter which reduces the risk of sink marks. Say hello to insert molding. Instead of doing assembly after the fact many sizes and types of metal inserts can be placed directly into the mold before plastic injection thus eliminating secondary operations and providing robust mating of metal and plastic. Cost because threaded inserts can be molded into the part at the outset or pressed into the part later consider the total cost of the operation.

Insert molding heatstaking and ultrasonic welding provide options to insert metal parts into your injection molded part. They can be used in more plastics including thermoset plastics while providing the highest most consistent pullout strength. Ultrasonic heat thermal press in and mold in. That includes molding time and cost component handling and assembly.

To better understand the trade offs here s a quick look at the four primary insertion processes. Our mb series threaded insert is designed to be molded into the plastic component during the molding cycle. We can also custom design and produce inserts for all applications. Typically the insert is placed on a core pin in the mold during the molding cycle.

Special features of injection molding inserts. Protolabs offers rapid insert molding. Inserts permanently encapsulated in the plastic section with only the threads exposed. We stock threaded inserts for these processes to support your unique design needs.

Threads as per international go not go standards. Engaged in the manufacture of brass threaded inserts for plastic and injection molding manufactures threaded inserts for plastics and precision machined products. Press in inserts series 50 symmetrical and series 51 headed press in inserts are designed to be pressed into a plastic hole without melting the plastic prior to installation. The insert is designed with aggressive knurling and undercuts to resist rotational and tensile.

Available in varying lengths for injection molding assemblies. Self tapping inserts are versatile. Heat staking threaded. Installing the inserts during the molding process eliminates the need for secondary steps or installation equipment.

Insert molding adds a preformed part often metal during the injection molding process. Iba ibb ibc blind threaded inserts page 12 iblc self locking blind threaded inserts page 13.
