As part of our turnkey manufacturing solutions, Longmax provides custom and insert-molded products for household, medical, automotive, and consumer electronics applications. With over three decades of expertise, we specialize in the design and manufacture of complex precision components and assemblies, particularly for the global automotive industry.

Our facility combines state-of-the-art equipment with advanced production technologies and a team of skilled engineers and technicians experienced in all phases of insert and plastic injection molding. Key highlights include advanced CAD design and manufacturing, tool and die-making capabilities, modern quality assurance testing, and a fully staffed in-house tool room with journeyman mold makers dedicated to maintenance and repair.

Our services:

• Product Evaluation & DFM Analysis: Engineers analyze part design and use mold flow simulation to optimize gate placement and catch defects early.

• Mold Design Engineering: Core/cavity layouts, cooling channels, and ejection systems are engineered to ensure cycle efficiency and long-term production stability.

• Tool Steel Selection: Materials like P20, NAK80, or S136 steel are chosen based on required durability, wear resistance, and production volume.

• Advanced CNC Machining: Multi-axis milling, high-speed machining, and EDM (Electrical Discharge Machining) create intricate features with extreme precision.

• Heat Treatment & Hardening: Applied to high-volume production molds to increase strength, wear resistance, and operational lifespan.

• Surface Finishing & Polishing: Custom finishes—such as mirror polishing, texturing, or bead blasting—are applied to achieve required aesthetics.

• Mold Assembly & Validation: Components are assembled for trial runs (T1 samples) to test dimensions, cycle times, and ejection before full production.
