Plastic injection molding is an important technology widely used in the field of plastic processing, and its processes are various and have their own characteristics. In the big family of injection molding technology, insert injection molding is a very special one.

Among the many defects of car fender injection molded products, weld lines are the most common. Except for a few automotive fender press die parts with very simple geometric shapes, weld lines occur on most car fender injection molded parts (usually in the shape of a line or a V-shaped groove), especially large and complex products that require the use of multi-gate car wing stamping dies and inserts.

Two-color injection molding is a technology of injecting two different materials into the same mold at the same time or separately. This process can save time and cost, because one mold can complete the injection of two different materials without additional steps and costs, such as assembly or fitter. In addition, by using two-shot injection molding, more complex parts or products can be produced because they can inject different materials into the same double shot injection molds. In this article, KRMOLD will introduce more information related to two-shot injection molding. If you have double shot injection molds purchase requirements, welcome to consult KRMOLD!

Micro injection molds are used to produce products with overall size, functional characteristics or tolerance requirements in millimeters or even microns. Because of the miniature characteristics of molded products, special molding machinery and auxiliary equipment are needed to complete various production operations. Such as injection quantity control, mold emptying (vacuum), injection, product ejection, inspection, separation, operation, storage, positioning and packaging. The manufacture of mold inserts and mold cavities also requires special technology.

In the manufacture of car glove box injection molds, it is crucial to choose the right material. The material of the automotive glove box injection mould not only affects the production efficiency, but also directly relates to the quality of the final product.

Car dashboard injection molding is a manufacturing process that produces parts by injecting molten material into automotive interior trim molds. This process occupies an important position in industrial production and is widely used in various industries. High-precision dashboard molds on the market are often made of hardened steel, pre-hardened steel, aluminum or beryllium copper alloy. There are significant differences in cost, wear resistance and service life of these injection molds of different materials, so customers can choose the appropriate automotive interior trim molds according to actual production needs.
