Rough surface/exposed fiber texture

Problem Phenomenon
Fiber woven texture is visible on the product surface, not smooth. Surface defects directly affect the appearance quality and usability of the product, and are particularly evident in transparent products. This defect affects the appearance quality of the product and reduces the market competitiveness of the product.
Cause Analysis
(1) Process factor: insufficient surface resin or excessive resin bleed-out exposing fibers; this factor affects the '2079851475616104453 and final quality of the product. (2) Mold aspect: poor mold surface finish; mold structure or condition directly affects the flow and molding of material in the cavity. (3) Process factor: release film wrinkles; this factor affects the '2079851475616104453 and final quality of the product.
Solution
(1) Formulation optimization: increase surface layer resin dosage; determine the optimal addition amount through small-batch tests, and verify the impact on the comprehensive performance of the product. (2) Equipment maintenance: use or replace high-finish molds; formulate regular inspection and maintenance plans to ensure the equipment is in optimal working condition. (3) Implementation measures: ensure the release film is flat and wrinkle-free when laying it., 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
Surface defects are the result of the combined action of mold condition, process parameters, and material formulation; each factor must be systematically investigated and targeted optimization performed.
