We have established a production system tailored to our customers' needs! We handle everything consistently from formulation design to production and shipping.
In the production and development of rubber products, we always have over 200 types of raw materials and chemicals on hand to create suitable formulation designs. During the mixing process, we use mixing rolls and kneaders to blend the measured compounds. The kneaded materials undergo physical property tests for each material lot to ensure quality. The sheeted materials cannot be used as they are, so they are cut or extruded to match the respective molds, bringing the cut and processed materials closer to the product shape. These materials are then placed into molds and shaped under specific temperature, time, and pressure conditions. Our company maintains a consistent process from formulation design to production and shipping, accommodating various applications. We have established a production system that meets customer requests, including short delivery times, mass production, and small batch production. 【Work Process】 ■ Formulation and formulation design ■ Mixing process ■ Material testing ■ Material preparation process ■ Molding and vulcanization process ■ Finishing process ■ Inspection and packaging *For more details, please refer to the PDF materials or feel free to contact us.

Synthetic rubber exhibits a wide variety of properties through various formulations! Here we introduce the advantages and disadvantages of rubber.
Rubber can be broadly divided into "natural rubber," made from the sap of rubber trees, and "synthetic rubber," produced from petroleum. As an elastomer, rubber contracts when force is applied and generates a restoring force when the force is released, but it does not completely return to its original state. This characteristic is influenced by the molecular chain structure of rubber. Rubber that exhibits contraction and restoration possesses exceptional properties for use as packing and seals. In addition, related links provide information on how rubber and plastics are made, as well as the characteristics of major synthetic rubbers. Please take a look. 【Advantages of Rubber】 ■ The unique "contraction and restoration" property of rubber ■ Some materials, despite being petroleum-based, have "self-extinguishing" properties *For more details, please refer to the related links page or feel free to contact us.
Is the rubber market centered in Asia? The history of transactions in Japan.
Rubber products, used for a variety of purposes from everyday items to industrial products, have become an indispensable part of our lives. The main sources of natural rubber are Thailand, India, Vietnam, and most silicone comes from China. Although rubber has developed primarily in Asia, its limited production areas make it susceptible to political influences, leading to significant price increases for natural rubber and silicone rubber. Additionally, synthetic rubber is derived from petroleum, making it subject to fluctuations in crude oil prices. Here, we will discuss the history of rubber exchanges in Japan, compare rubber production volumes with other Asian countries, and examine the demand for natural rubber and Japan's new rubber. For detailed articles, please refer to the related links below.
