On the surface of the hard material, an injection-molded flexible coating by glue or the like is used for the encapsulation.
With the upgrading of industrialization, the demand for comfort and shock absorption of various products has become stronger and stronger, and the demand for rubber packaging has also increased. on the surface different substrates have different adhesion. We must apply the adhesive through different formulations and rubber compounds. In order to develop the packaging of different substrates, we have studied various substrates, such as gold wheels, polyester, Allen, various metals, electroplating, plastics, etc., ABS, PPA, POM, PBT, PET, fiber and other substrates, rubber And various elastomers, processing technology, injection molding conditions, product appearance, surface, casting rod, adhesion, bonding strength, material strength, environmental indicators, etc. At the same time, we designed our own formulas, created test conditions, and met the customer’s small pilot test.
The processing line of covering wire equipment:
Lack of glue – increase processing injection temperature; increase injection pressure; improve logistics.
Quilting, overflowing – lowering the injection temperature; increasing the clamping force; lowering the injection pressure; reducing the fluidity from the formulation point of view.
Surface appearance, no light – increase injection molding temperature; bake, reduce raw material moisture.
Viscosity difference – fully bake before injection; increase injection temperature; adjust formula
Deformation of injection molded products – Strengthen mold cooling; Prolong the clamping time.
Product sticking mold – Add mold release agent or lubricant (for internal lubricant – release agent should pay attention to increase amount to prevent release agent migration and migration)
