Welcome to the new and old customers to visit! 400 * 200 * 80mm polypropylene raw material package-eight well-shaped plastic mold lawn brick mold, it can be used for municipal construction, residential landscaping, parking, park grass, plastic mold parts and other high-speed slope cracking cracking causes and solutions: primarily due to plastic mold material during stretching, beyond its limit strain formed instability. Fracture tensile strength less than 1 generated, such as test recess, corner garden lawn brick mold punch, local excessive force and rupture. 2. The amount is less material deformation and rupture the word lawn brick mold, in the bulging deformation test produced top punch rupture, or rupture elongation flange distortion caused by the inflow. 3. Aging cracks: the serious part forming hardened by strain aging embrittlement has increased fillet Wai Wai spent lawn brick mold, and late parts of residual stress caused by molding rupture. The material is stretched bending both folded but curved so as to produce rupture, produce more die in the ribs or mouth. 5. striped cracks. Because there are cracks caused by impurities in the material, generally parallel to the rolling direction of the sheet. Cracking Solution aspect 1. Material: plastic box with a good drawing properties of materials 2. Reduce strain areas: choose the right blank size and shape parameter adjustment drawbead adding auxiliary processes (incision, etc.) to improve the lubrication conditions modify addendum surface adjustment binder force the word lawn brick mold, lawn brick mold, mold provided by Baoding Guohui Guohui Die Machinery Co. Baoding Guohui Die Machinery Co., Ltd. (www.bdguohui.com) (www.bdguohui.com) strong, credible, in Baoding plastic building materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Guohui mold into the brilliant and you work for a better future!
