Doubling the durability of mold surface treatment in automotive motor parts manufacturing.
Durability improved by about 2 times! Dramatically enhanced productivity of injection molding molds.
■Issue In injection molding components, the durability of the mold surface treatment is poor, requiring frequent replacements and hindering productivity. ■Solution Gradually adjust a surface treatment that is resistant to wear from molten resin and has lasting effectiveness, adopting the optimal coating. ■Customer's Challenge A manufacturer of automotive parts faced the following issues in the injection molding process of motor components: ■Details of the Issue Even with surface treatment, epoxy resin adhered, necessitating replacement after about 2,000 shots. Frequent mold changes led to decreased productivity and increased costs. ■Conditions for Surface Treatment Selection Contact with molten epoxy resin under high temperature (150°C) and high pressure. Improving wear resistance is the top priority. ■Solution Method To improve the durability of the surface treatment, tests were conducted with multiple coating specifications to consider the optimal treatment. The following surface treatments were tested: - Bi-Coat NYK-11-S Durability comparable to conventional products - Bi-Coat TYS-03K Lifespan of a few hundred shots - Bi-Coat NYK-01 (Adopted) Durability improved to twice that of conventional products Recommended for those facing issues with resin adhesion prevention and wear-resistant coatings.
