What is insert molding process?

Insert molding is the process of putting inserts before injection molding. The finished product of insert molding is a single plastic part with an insert surrounded by plastic. Inserts can be made of metal or different types of plastics. Insert molding has been applied in many industries, such as insert molding couplings, thread fasteners, filters, electronic and electrical components.

The most advantage of the insert molding is cost-saving.
Insert molding is a highly efficient alternative to the assembly of discrete parts. It enlarges the performance of plastics and helps to reduce product costs by limiting the amount of expensive metals needed to produce products, also it reduces assembly and labor costs, and increasing design flexibility and part reliability.

We are professional in insert mold making. Sharing an insert mold made by Green Vitality used for electronic components.

What is the difference between TPU extrusion and injection molding?

Extrusion, also known as extrusion molding or extrusion, is also called extrusion in rubber processing. It refers to a processing method in which the material passes through the action between the barrel and the screw of the extruder, is plasticized while being pushed forward by the screw, and continuously passes through the machine head to make various cross-section products or semi-products. Injection molding is a method of producing shapes for industrial products. Products are usually injection molded from rubber and plastic. Injection molding can also be divided into injection molding and die casting. Injection molding machine, referred to as injection machine or injection molding machine, is the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes by using plastic molding die. Injection molding is realized by injection molding machine and mold.

Sprue Bush

The sprue bush is the connecting member between the machine nozzle and the mold face ，or can also be described as a flow path component that allows molten plastic material to be injected from the nozzle of the injection molding machine into the interior of the mold,and provides suitable aperture through which the material can travel on its way to the mould cavity or the start of the runner system in multi-impression molds.The bolt-type nozzle is a nozzle that is fixed by two bolts and is fixed by bolts to prevent the nozzle from falling off due to the injection pressure. The sprue bushing is often used as the grab point in robotic removal of parts, sprues and runners. This requires that the sprue be rigid enough to resist the pressure of the robot fingers as well as the extraction forces. With conventional steel sprues this measure is most often met by added cooling time to the mold cycle. HG Precision will again reduce the sprue coo...
