Strictly speaking, parison wall thickness uniformity control is the key to blow molding technology
The following four types of control are performed in the blow molding operation.
1 mechanical control: some control of the machine itself, such as temperature control and extrusion control.
2 process control measures and controls certain characteristics of the flow of plastics or plastics in machinery,
Such as melt temperature control, melt pressure control, parison wall thickness program control and parison length
control.
3 product control, measurement and control of certain characteristics of products formed by machinery, such as
Control of product quality and wall thickness distribution.
4 All mechanical control and management Monitor all the blowing machinery in the workshop
Bathing parameters ensure that all blow molding machines operate in optimal conditions and benefits, such as CAD/
CAM/CIM and so on.
The wall thickness of blow molded products is affected by many factors.
Manual adjustment is to set a certain number of screws in the circumferential direction near the outlet of the head.
The die is adjusted to the diameter, so that it produces a proper amount of elastic deformation.
The distribution of wall thickness ensures that the parison will fall vertically.
The axial thickness distribution also plays an important role in product quality. By turning the core mold
Nut to axially move the mandrel, can change die clearance, adjust the axial wall of the parison
Thick distribution. With or without thick-walled program control, the wall thickness of the product is uniform.
