Uneven product thickness
Problem Phenomenon
Thickness deviation of various regions of the laminate exceeds tolerance.
This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.
Cause Analysis
(1) Mold aspect: poor mold parallelism; mold structure or condition directly affects the flow and molding of material in the cavity.
(2) Process factor: uneven force during pressing; this factor affects the '2079851475616104453 and final quality of the product.
(3) Process factor: uneven material bedding during stacking; this factor affects the '2079851475616104453 and final quality of the product.
Solution
(1) Implementation measures: correct mold parallelism; formulate specific operation plans based on actual production conditions and verify implementation effects.
(2) Process control: use thickness limit blocks to control final thickness; establish an online monitoring mechanism, set parameter upper and lower limits and implement alarm management.
(3) Implementation measures: lay stacked materials uniformly., formulate specific operation plans based on actual production conditions and verify implementation effects.
(4) Preventive measures: establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.
Key Takeaway
This problem requires comprehensive analysis from multiple dimensions of materials, processes, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
