Uneven color/color difference
Problem Phenomenon
Inconsistent color on the surface or interior of laminated products.
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) Process factor: color differences between resin batches; this factor affects the '2079851475616104453 and final quality of the product.
(2) Temperature parameter aspect: local temperature deviation during curing causing resin discoloration; temperature deviation directly affects the physicochemical state and reaction progress of the material.
(3) Process factor: uneven resin content affecting light transmittance and color; this factor affects the '2079851475616104453 and final quality of the product.
Solution
(1) Material selection: use resin from the same batch; establish material selection evaluation standards and determine the optimal solution through comparative tests.
(2) Process control: control hot pressing temperature uniformity; establish an online monitoring mechanism, set parameter upper and lower limits and implement alarm management.
(3) Implementation measures: unify resin content., 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.
