BMC Product Post-treatment And Crate Mould Cleaning
(1) Post-treatment of products
The moulding shrinkage of the prefabricated integral moulding compound is very small, and the shrinkage and warpage of the product are not serious. For some products, if the above phenomenon occurs, it can be put into an oven for slow cooling to eliminate it.
(2) Product finishing
Because prefabricated integrally moulded products often have some burrs attached to them, they need to be removed. The maximum thickness of burrs shall be limited to 0.1 mm. If the thickness of burrs is too large, it will not only be difficult to remove, but also the material waste will be too large and the cost will be greatly increased. If time permits, the operator can clean burrs and holes on the product using tools such as cutting blades, embossing belts and press-in rods during the time interval between the closing and curing of the Crate Mould(FURNITUREMOULD). Smaller products usually use roller edges to remove burrs.
(3) Cleaning the crate mould
After taking out the product, carefully clean the crate mould. First of all, the residual prefabricated integral moulding plastic chips, flash and other chips in the crate mold should be completely removed, especially the materials that have penetrated into the gap of the joint surface of the cavity should be completely removed, otherwise, not only the surface quality of the product will be affected, but also the opening and closing and exhaust of the crate mould may be affected.
Compressed air, brushes and copper non-ferrous metal tools are usually used to clean the crate mould to prevent damage to the cavity surface during cleaning. After cleaning the crate mould, apply a certain amount of release agent to the area where adhesion may occur, and then carefully check whether there are other foreign matters in the cavity. After completing the above work, you can proceed to the next process.
