For high-performance parts, our materials of choice include PPSU, PEI, PEEK, and PPS.
For general-purpose parts, we commonly work with materials like POM, PC, ABS, PP, PMMA, and PA.
The major properties of plastic materials are listed above.
The number of mold cavities we construct is influenced by the part's complexity and the required production volume. Typically, we produce molds with 1 to 8 cavities. However, for exceptionally high-volume production of small parts, we can create molds with up to 64 cavities.
A family mold, also known as a multi-cavity mold, is a type of injection mold that is designed to produce multiple different parts or variations of a part in a single molding cycle. It allows for the simultaneous production of several different components using the same mold, increasing production efficiency and reducing costs compared to making each part separately. Family molds are commonly used in applications where multiple related parts are needed for an assembly or where different variations of a product are required.
Yes. If your annual usage is relatively low, we can produce multiple parts simultaneously on a single mold, effectively reducing tooling costs. While this approach may result in slightly higher part prices, it offers cost-effective solutions for certain projects.
Creating two-color molds offers benefits like improved aesthetics, cost efficiency, durability, and design versatility. It streamlines production, reduces post-processing, and enhances part quality, making it a versatile choice for various applications.
More about 2-shot molds.
The daily production output of a mold varies based on factors like the number of cavities and the molding cycle time. For instance, a 2-cavity mold with a 40-second molding cycle can produce up to 3,960 parts per day during 22 hours of operation.
Companies create backup toolings to minimize production downtime, respond quickly to design changes, mitigate supply chain risks, optimize mold maintenance, expand production capacity, enhance reliability for critical applications, and potentially save costs associated with downtime and emergency repairs.
