RHCM

Rapid Heat Cycle Molding,High gloss injection mold

RHCM applied in Computers / Communications / Consumer electronics.
RHCM applied in Computers / Communications / Consumer electronics.

Traditional plastic injection molding does often uneven surface gloss of products and floating or exposed fibers on the surface of the fiberglass reinforced plastic chassis、poor transferability、inject pressure excessive and inject pressure uneven that they make stress marks around the mold gate of the product.

Therefore, it is necessary printing and painting process to cover these surface defects. For high gloss products, insufficient brightness and uneven brightness cannot be covered by painting.

Therefore, FORESHOT develops and apply RHCM technology, not only solve the above problems but also solve traditional plastic injection molding in ultra-thin parts, thick parts and reduces the cycle time.

RHCM (Rapid Heat Cycle Molding) is rapidly changing the temperature of mold in injection process.This process is not only vanish the welding lines of the surface, but also improve the rate of product gloss and higher mold transferability.

High Gloss / Welding Line free Injection Molding with RHCM process is high-level technology, however, FORESHOT has been operated well in High Gloss / Welding Line free Injection Molding with RHCM process and invests many 250T ~ 1000T RHCM machines that they can do mass production and let customers satisfied.

FORESHOT adopts ARES high-gloss machine to provide advanced and stable RHCM technology and using of high-pressure water to instead steam in the water channel of the mold.

When the molds are matched in the injection machine then inject high temperature water and raise the mold temperature to the set value, and start injecting plastic into the cavity.

After the injection finished, injecting cold water let the mold temperature drops quickly to the set value. Open mold and blow air into the mold to blow away the cold water, finally complete the plastic injection molding process, as shown below.

    Insert Injection Molding

    Insert Injection Molding could be called Insert Molding or Over Molding, which a sole part is formed using two or more different materials in combination. In Insert injection Molding can either be incorporated at the time of the molding process or can be inserted as post molding operation. Especially, if properly selected two kinds of material, it will obtain a strong bonding of the molded part. Therefore, the used of primers or adhesive was no longer required to achieve an optimum bond between two materials. Foreshot according product requirements and design, through Insert Molding combines metal and plastics, or multiple combinations of materials and components into a single unit, this feature let customer enhanced design flexibility, such as Electronic Components、Precision Components and Vehicle Accessories etc.
