basic information
[Points to be Careful About During Processing] ■ Unlike general paper, this is a hard industrial paper, so if the thickness is 0.5 or more, it cannot be easily processed with a wooden mold (Thomson die). ■ It is necessary to perform press processing using molds, as we do. ■ In addition to generating paper dust during processing, it is prone to shrinkage and warping due to humidity, so attention must be paid to the processing environment and storage conditions. *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.
