We manufacture injection molded sheets measuring 100×100mm with a thickness of 1.5 to 4.0mm using original molds. Our injection molded sheet molds include options without markings in sizes of 60mm in width, 60mm in length, and thicknesses of 1.0 and 2.0mm, such as "JIS K7152-3." These can be used as test specimens for various applications, including impact tests and accelerated aging tests. Please feel free to contact us when you need assistance. 【Injection Molded Sheet Molds】 ■ Our Original: 100mm in width, 100mm in length, thickness of 1.5 to 4mm / without markings ■ JIS K7152-3: 60mm in width, 60mm in length, thickness of 1.0, 2.0mm / without markings ■ Our Original: 120mm in width, 80mm in length, thickness of 2.0mm / with and without markings *For more details, please refer to the related links or feel free to contact us.
