The injection molds designed and manufactured by KRMODL can meet the production needs of various different injection molding processes and meet the customized needs of customers in different industries for injection molding of plastic parts in terms of precision, output, shape, etc. Common injection molding processes include:
1.Conventional Injection Molding
The most common injection molding process, suitable for general plastic products. By melting plastic particles in a heated screw, the molten plastic is injected into the injection mold cavity through a nozzle, and the cooling water channel in the mold cools the plastic to solidify it, and the ejector or robot removes the injection molded plastic product.
2.Thin-wall Injection Molding
The injection mold uses thin-wall injection molding technology to produce plastic products with a wall thickness of less than 0.6mm. Common examples of injection molding molds include food packaging boxes and mobile phone cases. The thin-wall injection molding process requires high pressure and high-speed injection to ensure that the plastic completely fills the mold. At the same time, high requirements are placed on the injection mold cooling system to ensure that the product does not deform.
3.Two-shot Injection Molding
Two-shot Injection Molding is used to mold two or more colors/materials in one injection molding to improve the aesthetics and functionality of the product. Common injection molding processes include:
Turntable two-shot injection molding: the mold rotates 90°/180° to complete two injection moldings.
Stack Mold: two mold combinations to inject multiple materials at one time.
Insert two-shot injection molding: first inject one material and then coat another material.
4.Gas-assisted Injection Molding
The gas-assisted injection molding process uses high-pressure gas to blow into the cavity to form a hollow structure for the product and reduce material usage. This type of injection mold is suitable for thick-walled products to prevent dents and deformation, reduce product weight, and reduce material costs.
In addition, common injection molding processes include Overmolding, Multi Cavity Injection Molding, and Micro Molding.
