FUJI SEIKI Co.,Ltd Product Lineup

The "Durable Molds" from Fuji Seiki are designed with high quality backed by a durability record of over 10 million shots. With more than 650 maintenance cases for molds produced between 1996 and 2005, including repairs and spare parts support, we achieve long life and stable operation. Furthermore, by thoroughly implementing the following five precision management practices, we ensure even greater molding stability and longevity. ■ Features - Heat treatment management using in-house quenching equipment: Processed under optimal conditions for each part - Thickness precision of mold bases managed to ±5μm: Stable mold alignment accuracy - High-precision measurement of part dimensions and traceability: Minimization of defect rates - CAE calculation design of clamping pressure receiving surfaces: A robust structure that withstands resin pressure - Optimal gas vent structure design: Reduction of molding defects and corrosion risk measures *Please feel free to contact us for more details, as this may vary depending on the molding materials.

We would like to introduce our molds that reduce maintenance costs. As a "gas venting measure for plastic molds," we install appropriate air vents and air grooves according to the resin used and the shape, achieving a structure with high gas venting efficiency. We also consider the balance of protrusions after molding, setting clearances for each resin, and selecting appropriate steel materials and surface treatments for parts that operate and slide to ensure corrosion and wear resistance, implementing "wear and galling measures." Additionally, we conduct "in-house heat treatment" for the purposes of suppressing aging changes, improving wear resistance, and stabilizing hardness. We always consider the assembly and disassembly of molds, designing them for easy maintenance. *For more details, please refer to the PDF document or feel free to contact us.

One of the reasons why maintenance of plastic molds is necessary is that gases generated during molding can liquefy and adhere to the mold. Fuji Seiki's plastic molds and precision molds are designed with appropriate air vents and air grooves according to the resin used and the shape, achieving high gas venting efficiency. Currently, we are offering technical materials that can help reduce mold maintenance costs.
