This is an introduction to thermosetting plastic molding. If you have a source for thermoplastic requests but are looking for a source for thermosetting plastic, or if you are seeking advice for the first time, please feel free to consult with us. Our company is capable of handling various molding methods for thermosetting plastics as follows: 【Molding Methods】 ■ Compression Molding ■ Transfer Molding ■ Injection Molding ■ Epoxy Casting, Vacuum Epoxy Casting ■ Insert Molding Below are representative materials. 【Materials】 ■ Epoxy ■ Melamine ■ Phenolic ■ Urea ■ Unsaturated Polyester ■ Diallyl Phthalate Please consult with us first. 【What is Thermosetting Plastic?】 There are two types of plastics: thermosetting and thermoplastic. As the name suggests, thermosetting refers to materials that harden when heat is applied. Conversely, thermoplastic becomes soft when heat is applied and solidifies when cooled. A common analogy is that thermosetting is like cookies, while thermoplastic is like chocolate.

Introduction to Foam Injection Molding and SF Molding. Foam injection molding and SF molding involve molding resin pellets with a chemical foaming agent. A skin layer is formed on the surface, while a foamed layer is created in the core section. Since the inner layer is foamed, it allows for weight reduction. Additionally, the injection pressure can be lowered compared to conventional injection molding, which minimizes deformation and sink marks despite the thick walls. **Benefits of Foam Injection Molding and SF Molding** - Capable of molding large and complex shapes. - Achieves weight reduction despite thick walls. - Reduces sink marks, warping, and distortion compared to conventional molded products. - Compatible with a wide range of thermoplastic resins. **Product Examples** - ATM covers. - Bases for analytical instruments (replacement from metal). - Top covers for analytical instruments (integration of components). - Cost reduction and weight reduction from metal covers. - Cost reduction and weight reduction from die-cast products.

We can accommodate everything from prototypes starting from one piece to mass production of 100 pieces or more. 【Ceramics Processing】 Ceramics are very hard materials. To minimize processing, we start from sintering the material, working from shapes or diameters that are as close as possible. Therefore, the lead time can take some time, typically around 4 to 6 weeks. To respond to urgent requests, we have certain types of materials in stock that can help shorten the time from material sintering, depending on the size. We are open to consultations based on your usage situation. 【Glass Processing】 We can also handle tasks such as applying anti-shatter film. Please feel free to contact us.
