✨Injection Molding of ABS Resin Case Study Part 1: Injection Molding✨

To prevent water leakage in rubber molded products, we received a request to attach a packing, and we proposed using Eptsealer tape, which has high waterproofing properties. When we created a prototype in the shape of a ring with a slit in one place, there were concerns about water leakage from the slit, so we consulted again about the shape for manufacturing. We proposed a new design by adding a slit to the inner diameter of the ring to eliminate the seam, making it possible to attach it to rubber products as well. We were appreciated for our precise solutions to the concerns and the high level of our processing technology, and our processed products were adopted.

This is a highly flexible Eptsealer that shuts out vibrations, sound, water, and other disturbances by being applied in the gaps between materials, products, and machinery. It is primarily composed of EPDM rubber, which offers heat resistance and chemical resistance (to acids and alkalis), providing excellent performance among general-purpose rubbers. Thanks to advanced foaming technology, it has become a low-density and flexible foam material. The cell structure comes in two types: independent bubble type and semi-independent semi-continuous bubble type, allowing it to meet various demands through different foaming techniques. It is effective in areas exposed to intense impacts and vibrations, such as door mirrors, tail lamps, air conditioners, and door speakers.

✨I wonder what kind of material would be good to use here? A high-performance sponge that can withstand heat, absorb shocks, and meet various other requirements!✨ "PORON" is a high-performance urethane foam with a high density, extremely fine, and uniform cell structure. It has very low compression set, excellent sealing properties, and superior thickness and dimensional accuracy. Additionally, it excels in energy absorption and is a material that is hardly affected by contamination. Kōnan Co., Ltd. provides various processing methods using the high-performance sponge PORON for our customers. Examples include: - Mobile devices - Automotive parts - Feet for furniture (chairs, TVs, etc.) - Consumer products (shoes, sports equipment) - Civil engineering and construction - Railways and aircraft, among others It is also active in various other fields.

Elastomers and ABS resin, which can be processed like plastic Elastomers and ABS resin are materials that can adapt to various shapes, and by combining these two, the range of products can be further expanded. Basic Information An elastomer refers to a polymer material that has properties intermediate between rubber and plastic, specifically a thermoplastic material that can be processed like plastic and exhibits significant elasticity. ABS resin is a type of synthetic resin, a general term for copolymer synthetic resins made from acrylonitrile, butadiene, and styrene. The name ABS is derived from the initials of the raw materials. The common heat resistance temperature is between 70 and 100°C.
