Embossing mould are required to comply with DIN 6784. What is this standard?
When embossing dies are required to comply with DIN 6784, this primarily refers to adherence to this German industrial standard for edge processing of the mold workpiece. This is specifically reflected in the following aspects:
Mold Edge Processing Specifications
Chamfering: Some edges of embossing dies are chamfered to avoid stress concentration and prevent cracking caused by frequent stress during use. For example, the edges of cavities and raised features must comply with the DIN 6784 standard for the corresponding mold type and usage scenario. This helps improve the lifespan and stability of the mold.
Chamfering: The edges of mold parting surfaces and mounting holes are typically chamfered according to standards. For example, when the mold is installed on an injection molding machine or stamping press, a chamfer of appropriate angle (such as a common 45°) and size is machined to facilitate installation and prevent damage to machine components. This reduces friction during installation and reduces the risk of mold edge cracking. Chamfering: After the embossing die is processed, burrs may remain on the surface. Chamfering can remove these burrs and make the die surface smoother. This not only helps improve the aesthetics of the die, but also prevents burrs from adversely affecting the surface quality of the embossed workpiece during use.
