Basic knowledge of insulating materials you should know before selecting and processing materials! Introducing thermal bending processing.
Our company, Yamada Manufacturing Co., Ltd., has built a long-standing trust and track record with our customers in the field of non-metallic resin pressing due to the uniqueness of this area. We will introduce basic information and know-how regarding the processing of insulating materials from a perspective that only we can provide. Please read this before selecting materials or processing. We will present know-how for bending insulating materials using "thermal bending processing." This method involves applying high heat to the material or mold to soften the material before applying pressure, a technique not commonly seen in the bending of metal materials. The reason is that when bending metal, heat is generated due to the pressure applied. Since insulating materials like paper and resin do not reach high temperatures, it is necessary to apply heat through a different principle. [Features] ■ When you want to bend at a large angle (around 90°) or when the material is prone to spring back, applying heat can effectively maintain the angle. ■ Thermoplastic resins become less prone to cracking when heat is applied. ■ It is possible to "condition the material and maintain its shape" by applying heat after bending. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Points to be Careful About During Processing】 ■ If too much heat is applied, there is a risk of combustion for industrial paper, and for resin, it can become too soft, brittle, and prone to cracking. ■ Since it also affects the bending angle and dimensions of the product shape, temperature settings and processing conditions appropriate to the material are necessary. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Yamada Manufacturing is a leading company in non-metallic resin pressing, primarily focusing on the processing of Bakelite, and we deliver a wide range of products such as resin press parts and insulating parts to the automotive industry. Bakelite processing utilizes a variety of materials, including paper and fabric substrates, as well as our mainstay glass substrates. Our products are increasingly being adopted in automotive electrical components, electronic device parts, and more recently, in electric vehicle components, which has garnered us further patronage. Additionally, we have a proven track record in processing a diverse array of materials, including thin film products, melamine, and rubber. In recent years, we have also achieved cost reductions through shape processing of adhesive-backed materials and by applying adhesives to substrates in-house before shape processing.
