>> Die, molding and parts of the work surface should be smooth and there should be no bumps, scratches, burrs, and attachments, as well as corrosion and other defects.

Die >> melt flow direction flow system should be gradual, try to avoid sections of mutation and residuum.

>> The template should have a reliable location, between the loading and unloading of the template correspond to positions between repeatability error is not greater than 0.03mm; plastic profile extrusion tooling die head the jointing surfaces and flattening should be a good fit, its local clearance shall not be greater than 0.02mm.

>> Molding cooling systems, vacuum systems that often, does not leak, water systems under normal circumstances should not collude. Fittings of plastic profile extrusion calibrator, vacuum fittings should be clearly marked and should not affect the piping connections.
