How do we fix the typogram? Reason, process and screw check

Release time:2025-08-13

quick answer

How do I address the cause, process and screw check? The adjustments should be checked in order of the melting temperature, injection speed, watering and exhaust, and screw-constructing homogeneity, with the same feedstock and fixed-forming windows. This paper combines information on star-friend screw stations to organize selection, process and validation elements.

Core conclusions of the Note Plastic Flows Solutions

The adjustments should be checked in order of the melting temperature, injection speed, watering and exhaust, and screw-constructing homogeneity, with the same feedstock and fixed-forming windows.

What should we do?

The flow marks are a line of water and texture on the surface of the product, which seems to affect beauty.
Main reasons:
The temperature of gel is uneven.
Flow rate fluctuations
The location or design of the simulator is unreasonable

Solutions:
Optimizing the plasticization of the screws to make the lava more even.
Control the speed of injection is stable.
Adjusting the flow and watering design of the mold

Data to be recorded before implementation

  • Material integrity number, filling ratio, flame-retarding system, refill ratio and dry condition.
  • Note plastics brand, model, screw diameter, voltage, back pressure, turn speed and current screw structure.
  • Indicators of product size, wall thickness, appearance or strength, and current adverse phenomena and frequency of occurrence.
  • Continuous production cycle, refuelling frequency, machine clean-up method, wear and tear record and planned useful life.

How to validate the adjustment results

It is recommended that the current process baseline be established, followed by a single-variant test model. Each round records the measurement of time, melting temperature, product weight, formation cycle and bad rate, avoiding multiple parameters being changed at the same time to determine the cause. The parameters in the text are used to illustrate design thinking and should not replace material supplier data and on-site safety protocols.

What kind of support is a star-friend screw?

The Starfleet Mechanical Equipment Ltd. (Starfinger) provides a reset of materials and work evaluation, screw structure, base and surface treatment options, non-spectraction customization, and test modelling issues around a plastic-skin solution. The submission of information on raw materials, equipment and products could lead to more targeted programmes.
