KRMOLD provides prototype injection mold design services, with nearly 20 years of design and production experience in the professional team to communicate with customers on product requirements, assess the feasibility and develop technical solutions, combined with CAD, CAM and other design software for injection mold 3D modeling and mold flow analysis to optimize the structure of the injection mold.

KRMOLD has a complete system of injection mold manufacturing workshop, precision manufacturing of injection molds involving pen, including Japan Makino CNC machining, electric discharge machining (EDM), wire cutting, drilling, grinding and other internationally renowned brands of processing equipment, combined with high-precision secondary and tertiary coordinate detector testing equipment to ensure that the mold micron-level accuracy.

KRMOLD is equipped with professional injection molding machines in the factory workshop to provide injection molding service and adjust the mold parameters according to the results. After the production of injection molds, KRMOLD carries out the assembly, installation and injection molding process in the factory, and adjusts the ejector pin position to reduce the deformation of the products or optimizes the cooling system to shorten the molding cycle for the problematic injection molded products.

Insert Molding is a process in which the insert is pre-fixed in the appropriate position in the injection mold, and then the plastic is injected for molding. After the mold is opened, the insert is tightly buried in the plastic by the cooled and solidified plastic to obtain a product with inserts such as threads and electrodes. The positioning of the insert in the mold needs to be achieved through a positioning boss or a floating positioning pin. The positioning boss of the injection mold needs to cooperate with the plane of the insert. For threaded inserts, the floating positioning pin is supported by a spring to accommodate dimensional errors, and the shoulder diameter is larger than the insert diameter to prevent overflow.

Overmolding is an injection molding technology in which one material is molded over another material to form a single part. This process involves multiple injection molding steps, each of which adds a new layer of material to the previously molded component. Overmolding provides flexibility for designing products with different physical, tactile and functional properties, usually combining rigid and flexible materials.

KRMOLD provides multi-cavity injection molding molds, multi-cavity injection molding can make multiple parts simultaneously in one mold. The design of the mold ensures uniform flow and quality of all parts. Important components include mold base, runners, gates, and injection system. They work together to make precise products.
