一、简述 锌钢模具是在锌合金模具的基体上,综合钢模与锌合金模的优缺点而发展起来的一种新的制模技术。从85年以来,经过反复进行工艺试验和生产验证,实践证明,这种制模技术不仅制模工艺简单凋期短、成本低,而且使用寿命较长,冲压件质量高,非常适合中小型企业进行中小批量生产,尤其适合于中小企业汽车车身大型覆盖件生产。 First, a brief description Zinc steel mold is the matrix of zinc alloy mold, the advantages and disadvantages of integrated steel mold and zinc alloy mold developed a new modeling technology. Since 85 years, after repeated process test and production verification, the practice proves that this molding technology not only has the advantages of simple die-making process, short withered period, low cost, long service life and high quality of stamping parts, and is very suitable for small and medium-sized enterprises Small and medium-sized batch production, especially for small and medium-sized car body cover production.
