Its stated product scope covers mold accessories, mold materials, bench drill accessories, machine tool accessories, and guide-related mold parts. The supplier reports ISO9001:2015 and CE certifications, 3D software design services, broad customization options, 10 R&D engineers, and new product development during the past year. It has exported for 11 years, with exports representing 31%–40% of sales.
