In the design and production technology of molds for resin and rubber molding, are you struggling with poor resin release during molding, leading to defective products and frequent mold cleaning? By applying a surface treatment that imparts excellent release properties and non-stick characteristics to the mold surface, it is possible to fundamentally prevent resin adhesion and dramatically improve production efficiency. Our "Electroless Nickel PTFE Coating" is a composite surface treatment that uniformly disperses fluororesin (PTFE) within the plating film. The PTFE content can be adjusted according to the application, providing water-repellent, oil-repellent, and self-lubricating properties. This significantly reduces maintenance frequency and contributes to improved yield. 【Solutions to Your Problems】 - Resin or rubber adheres to the mold after molding, resulting in poor release properties. - You want to reduce the labor involved in mold cleaning and maintenance. - You want to lower the defect rate of products and improve yield. *For more details, please download the PDF or feel free to contact us.
