Keep the room temperature constant and carry out the chemical reaction over 24 hours! Introducing the general adhesive process for polymer bonding.
We will introduce the bonding process of "polymer adhesive." First, a gasket about 5mm thick is placed between the acrylic sheets. This creates a space for pouring the adhesive between the sheets and a wall that seals the space to hold back the adhesive. Next, the adhesive is poured in, a chemical reaction occurs, and stress is removed through heat treatment. The acrylic is allowed to cool slowly and naturally until it is nearly the same temperature as the outside air, and then it is processed into the desired shape. Most products are finished in a clean state from the start, so they are not polished much unless there are scratches. However, if bending processing is done, marks from the mold will remain, so polishing is generally performed. Depending on the product's application, precision and appearance may be inspected visually or with instruments. Please feel free to contact us if you have any inquiries. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Founded over 60 years ago, Shinshi Co., Ltd. is a pioneer in plastic (resin) sheet processing, possessing the technology to consistently perform bending, cutting, grinding, adhering, and polishing. It is one of the few companies in the acrylic processing industry that has both molding technology and cutting and bonding technology, collaborating from rough sketches before they are drafted. The range of services includes large molded products (one of the largest in the industry for vacuum forming, press forming, and air pressure forming) to secondary processing (cutting, bonding, surface treatment, etc.). In the aquarium industry, since the use of acrylic panels, we have collaborated with Mitsubishi Rayon (Hishiko) for many years to produce acrylic panels for aquariums both domestically and globally, accumulating a wealth of achievements. We have also been manufacturing three-dimensional molded signs and components for amusement devices by combining screen printing and molding for many years. Other products include medical devices, electronic equipment, construction materials, objects, and spatial displays. For inquiries regarding prototyping, small lots, mass production, short delivery times, and low costs, please consult Shinshi, which has abundant processing technology.
