明石プラスチック工業 List of Products and Services

Introducing our "Thermosetting Compression Molding Division." We perform compression molding of materials such as phenolic resin, which excels in heat resistance, electrical resistance, and chemical resistance. Compression molding has the advantage of not producing weld lines (the joints of the resin) that can easily cause breakage, as the material is heated after being placed in the mold. We have a long track record in automotive insulation parts (non-conductive), pulleys, insulators (epoxy, BMC), and terminal blocks (phenolic, BMC). 【Materials Handled】 ■ Phenolic resin ■ Epoxy resin ■ BMC ■ Urea resin ■ Diallyl phthalate resin, etc. *For more details, please refer to the PDF document or feel free to contact us.

Akashi Plastic Industry is a specialized plastic manufacturer that consistently handles everything from mold manufacturing to injection molding and compression molding of thermoplastic and thermosetting materials. We have developed pulleys for power transmission, commonly used in automobiles and industrial machinery, from thermosetting resin instead of the conventional metal, achieving lightweight and low noise. Among thermosetting molding methods, we particularly use "compression molding," which involves placing the material into the mold and then solidifying it. This method eliminates seams in the resin that can cause cracking, resulting in higher strength. It is also cost-effective and offers expanded possibilities for products. <Recommended for those facing these issues!> Want to prevent belt wear, convert metal to resin Looking to reduce weight, minimize noise, prevent rust, and lower costs, etc. 【Features】 ■ Lightweight (1/4 the weight of iron, 2/3 the weight of aluminum) ■ Quiet (achieved noise reduction from 69dB to 65dB) ■ Lower cost compared to metal (for diameters over 100mm) ■ Heat-resistant (can withstand high loads at 150°C due to thermosetting production) ■ Rust-resistant *For more details, please refer to the PDF document or feel free to contact us.

Akashi Plastic Industry Co., Ltd. is a specialized plastic manufacturer that consistently performs thermoplastic and thermosetting injection molding and compression molding from mold manufacturing to molding. We possess advanced technology, particularly in thermosetting molding. The "thermosetting resin pulleys" developed by Akashi Plastic Industry have strength and performance comparable to metals such as iron and aluminum, while being lightweight and accommodating small lot orders. If you are considering weight reduction and cost savings while using metal ribbed pulleys or timing pulleys, please feel free to inquire. 【Features of Thermosetting Resin Pulleys】 - The heat resistance temperature of thermosetting resin is 150°C, adequately handling high loads. - With a specific gravity of 1.8, it weighs about 1/5 of iron. - Noise reduction is possible (e.g., 69.0dB ⇒ 65.8dB). - Lightweight allows for rapid acceleration and deceleration. - Reduces belt wear. - No rust prevention needed (does not rust). - Can be supplied in lots of 50 pieces for shaft diameter key dimensions, etc. (limited to continuous purchases).
