1. The fitter stage of automotive mould The fitter stage of the automotive mould includes: mold benchmarking - mold clamping - mold trial - sampling, etc. After the NC processing of the automotive mould, there is still a certain margin for the follow-up fitter. The fitter debugging mainly checks the lapping-in rate of the upper and lower molds and the oriented lapping-in rate so as to ensure that qualified stamping parts are stamped out. Through mold fitter debugging, the quality of automotive moulds can be identified, and the size of the blanks can also be determined. 2. Pre-acceptance of automotive moulds After the mold factory completes the production of all contracted molds within the planned time and passes the self-commissioning, they can apply for pre-acceptance to the development department of the OEM. The mold factory needs to provide the self-inspection report of the automotive mould and the pass rate of the stamped parts. After receiving the pre-acceptance application ...

Oct 10-2020 Views: 638 1. What is the effect of the deep sill (drawing rib) in the cover mold? The effects of the deep drawing threshold (drawing bead) are as follows: 1. Increase the friction resistance of the feed material, so that the surface of the deep drawing part bears sufficient tensile stress, improve the bending stiffness of the deep drawing part and reduce the concave surface, distortion, slack and wave pattern caused by the resilience; 2. Adjust the fluidity of the material to make the fluidity and frictional resistance of each part of the whole drawing process equal, or make the amount of material injected into the mold suitable for each part of the steel part to avoid the situation of "less wrinkles, less cracks"; 3. Expand the scope of adjustment of the hemming force. On the double-action punching machine, adjusting the height of the four corners of the outer guide rail slider only roughly adjusts the hemming force, and it is not possible to control t...

Selective Laser Sintering (SLS) is an industrial 3D printing process ideal for manufacturing end-use parts. In SLS 3d system, a laser selectively sinters polymer powder particles, fusing them together and building a part layer-by-layer. From SLS rapid prototyping to small-batch production, our SLS 3D printing facilities will allow you to produce highly accurate parts, with low cost and high quality comparable to injection molding. SLS produces functional plastic parts with isotropic mechanical properties that can be used for detailed prototyping or end-use low-volume production. Size of selective laser printing Below table shows the size of Fused Deposition Modeling parts we usually make. If you need a larger size, we can also help you achieve it. Standard capabilities Description Maximum build size * 300 x 300 x 300 mm (11.8” x 11.8” x 11.8”) Lead time * 6 business days Dimensional accuracy ± 0.3% with a lower limit of ± 0.3 mm (± 0.012”) Layer thickness 100 μm * For expedited le...
