Buyers usually arrive with a part that has already failed somewhere \u2014 a panel that warped after machining, a plate that delaminated at the edge, or a surface that looked right until it was polished. This page sets out what we press, what we control, and what you should specify before tooling is cut.<\/p><\/blockquote>\n\n\n

What we press<\/h2>\n

Carbon fiber laminates are made by impregnating carbon fabric or unidirectional reinforcement with resin, then consolidating under heat and pressure in a matched mould. We press to specification, which means thickness, resin content and surface finish are set by our process rather than negotiated with a third party.<\/p>\n\n

Why thickness tolerance is the number to argue about<\/h2>\n

Most laminate complaints we see are not about strength. They are about thickness.<\/p>\n

A laminate is pressed to a nominal thickness, but the achieved thickness depends on fibre areal weight, resin content, ply count and mould closure. Two consequences matter commercially:<\/p>\n

    \n
  1. 1.0 mm \u677f\u6750\u4e0a \u00b10.1 mm \u7684\u504f\u5dee\u5c31\u76f8\u5f53\u4e8e 10%\u3002<\/strong> If your assembly has a fixed slot, that band may be the difference between fitting and rework. Specify the tolerance you actually need, not a round number.<\/li>\n
  2. \u673a\u52a0\u5de5\u4f1a\u66b4\u9732\u6750\u6599\u5185\u90e8\u3002<\/strong> Drilling and edge trimming cut through plies, and a poorly consolidated interior shows up as fuzzing or delamination at the cut edge. If the part will be machined, tell us at quotation stage \u2014 we press and cure with that in mind rather than treating it as a finishing operation.<\/li>\n<\/ol>\n
