Many Molds In addition to product developers should try to save mold costs, but also applied the most popular innovative technology “Many MIS“. “Many MIS” is widely used in many fields. On the premise of the larger the number of objects, the more money you save. In most cases, the less expensive tools are of lower quality, less durable, have looser tolerances, and have poorer surface finishes. These are not cost savings. Instead, they are costly mistakes. Instead, long-term savings can be realized through increased productivity, shorter cycle times, and process stability. As volume increases, the relative cost of the tool decreases until it’s virtually free.

Cost Saving for Injection Molding (Especially for Mass Production), Multiple Innovative Injection Molding Solutions, Innovative Mold Design + Innovative Mold Steel, Self-developed Integrated Intelligent Control Systems and Equipment, Our molding service is strengthened by our extensive expertise and a wide range of production capabilities. This means we’re capable of producing parts ranging from millimeters to cubic meters in size. Our production of such a wide variety of parts enables us to best meet your needs. Further, we have unique access to tooling experts with decades of experience. They are available for video conferencing and customer support. We’re united in our efforts to help you have a satisfactory injection molding experience!

This depends on the complexity of the tool design and the type of material the tool is made from. Generally speaking, a very basic square shape made from relatively soft steel such as P20 can be made in less than one week. Very hard steels take longer to cut and heat treat, while complex shapes or advanced surface textures can require three or more weeks to prepare.

A reputable manufacturer will positively identify all incoming raw materials, and will carefully control every stage of production to ensure process repeatability. Full ISO certification is a good demonstration of their commitment to excellence.

We make tools and dies from S136H, 2316H, H13 hardened, 2316H, P20, 8407, and NAK80 semi-hardened steels. We offer standard SPI finishes, EDM texturing, and several different types of etched textures. We also have thousands of thermoforming plastics available – contact us for details.

All orders are carefully reviewed by our tooling engineers to provide design for manufacturing optimization. We also work closely with outside design consultancies who can offer expert advice on the process of moving a product from the concept stage to production-ready.

Our quality-control system includes several steps to ensure safe, high-performing products for our clients. As with all of our services, we conduct comprehensive material verification and testing before molding begins. This includes the metal used in our molds and the plastics used in production. During production, we carefully control all processing conditions — including temperature and humidity — to maintain repeatable results. Many molding companies neglect to do this, which can lead to flaws in the finished parts. We also 3D scan complex shapes to ensure accuracy.
