Injection Mold Process
A custom tool for molding must first be created before a custom injection mold can be made.
The first step in this process is to work with our clients to create and revise the product blueprints. This process is done through CAD (computer aided design) to ensure that the end usage, materials required, and expected production volume are all accounted for before the development of precision tooling. Computer modeling allows the designer to develop the shape of the mold, simulate the injection molding process, and visualize (through simulations) the flow of the polymer into the mold cavity. These simulations prevent miscalculations and product deformities from occurring in the production process.
One the mold design is confirmed, the mold is created using CNC (computer numerical control) equipment. While CNC is the most efficient way of creating complex mold patterns, Hung Kuan also offers hand crafted customization and enhancements. During this process, features such as vents will be added to the mold to ensure optimal material flow and curing.
Once the molding tool is created, we apply surface finishing and heat treatment processes to ensure maximum longevity for the tool. This entire process is inspected multiple times to ensure the quality and accuracy of the molding tools that we make. Hung Kuan’s ISO 9001:2008 certification guarantees that quality management systems along with appropriate controls are in place through the entire molding process including monitoring for wear and tear and routine maintenance even after the molding tool is created.
With Hung Kuan’s in house tooling department, all designing and implementation of new molds as well as modifications or repairing of existing molds are always done on site. Whether the mold was created by us or not, our tooling department can modify and repair molds and bring them up to production quality.
