Analysis Of The Causes Of The Shock Pattern Of Injection Molded Products In the manufacture of rigid plastic parts, the surface near the gate forms a dense corrugation centered on the gate, sometimes referred to as a shock pattern. The reason is that when the melt viscosity is too large and the mold is filled…
Analysis Of The Causes Of Welded Joints In Plastic Products The molten plastic in the cavity meets in the form of multiple strands due to the intrusion of the insert holes, the discontinuous flow rate, and the region where the filling flow is interrupted, and a linear weld seam is produced because it cannot be…
Extrusion Blow Mold Processing Technology Mold material is the most important factor in determining the manufacturing method. Aluminum is difficult to cast and only certain aluminum alloys can be cast. In general, aluminum alloys with high silicon content are most suitable for casting, while high-strength aluminum alloys cannot be cast, and mechanical processing methods are…
