Uneven Surface Tackiness of the Product
Problem Phenomenon
Part of the product surface is sticky while other areas are normal.
This problem directly affects the mechanical properties and surface quality of the product, and in severe cases leads to the scrapping of the entire batch of products.
This defect affects the appearance quality of the product and reduces the market competitiveness of the product.
Cause Analysis
(1) Process factors: uneven mixing of curing agent/accelerator causes local under-curing, this factor affects the product's '2079851475616104453 and final quality.
(2) In terms of temperature parameters: uneven mold temperature causes differences in curing degree across regions, temperature deviation directly affects the physicochemical state of the material and the reaction progress.
(3) Process factors: local excess of release agent affects curing, this factor affects the product's '2079851475616104453 and final quality.
Solution
(1) Process optimization: extend the mixing time to ensure uniform mixing, determine a reasonable time based on product wall thickness and material characteristics, balancing production efficiency and quality.
(2) Equipment maintenance: check the temperature uniformity of the mold heating system, formulate a regular inspection and maintenance plan to ensure the equipment is in optimal working condition.
(3) Implementation measures: standardize the release agent application operation., formulate a specific operation plan based on actual production conditions and verify the implementation effect.
(4) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.
Key Takeaway
The core of the poor curing problem is that the chemical reaction conditions are not met, and the formula ratio and curing process parameters need to be precisely controlled.
