Carbon fiber & glass.碳纤维与玻纤
Hand layup, compression molding, and autoclave cure for structural composite parts. Two autoclaves cure T700 and T800 prepregs at 6 bar and 180°C. Post-cure CNC trim and assembly happen in the same complex — composite parts remain in-house from cure to ship.
From cold storage to cured part.从冷藏室到固化件
Composite manufacturing depends on cold-chain discipline, clean-room layup, and cure-cycle control. The composites building is organised end-to-end from refrigerated prepreg storage through bagging, autoclave, and post-cure CNC trim — all in one building, all in one controlled environment. 复合材料制造依赖冷链管理、洁净室铺层与固化周期控制。复合材料厂房按从头到尾的顺序布置——从冷藏预浸料存储、真空袋封装、热压罐固化，到固化后 CNC 修边——全部在同一栋楼内、同一受控环境中完成。
Layup & vacuum bagging.铺层与真空袋压
The stack-up is the part. Ply orientation, ply count, and consolidation quality drive every mechanical property the customer cares about — stiffness, strength, fatigue life, surface finish. We hand-lay every production part in a Class 7 clean-room with documented ply-by-ply traceability. 叠层即零件本身。铺层方向、铺层层数、压实质量决定客户关心的每一项力学性能——刚度、强度、疲劳寿命、表面光洁度。我们在 Class 7 洁净室内手工铺贴每件量产零件，每一层均有可追溯文档记录。
Controlled, repeatable, ply-by-ply documented.受控、可重复、逐层留档
Automated tape laying (ATL) is faster, but it works for big flat aerospace skins — not for a compound bow limb with a thirty-degree taper or a stabilizer with a transitional cross-section. For the parts our customers ship, hand layup is the practical method for this geometry without compromising layup schedule. We invest in training and clean-room discipline instead.
Plies are cut on CNC drag-knife tables (Zünd G3, Eastman M9000) from CAD-derived nested kit patterns — eliminating hand-template error, maximising prepreg utilisation, and generating the build record automatically. Each kit ply is barcode-indexed against its parent roll, out-time-stamped, and laid by trained operators against a tool datum. Aerospace programs run with RFID-tagged ply kits — every ply that goes into the part is logged into a build record that travels with the program. 铺层片在 CNC 划刀台（Zünd G3、Eastman M9000）上按 CAD 排版套料切割——消除手工模板误差，最大化预浸料利用率，自动生成生产记录。每片均按母卷条码索引，标记出袋时间，由经培训的操作员对照工装基准铺设。航空航天项目采用 RFID 标签铺层套件——每一片进入零件的铺层片都计入随项目流转的生产记录。
Autoclave cure.热压罐固化
Out-of-autoclave (OOA) processes have improved substantially, but for structural carbon parts where void content and fiber-volume fraction matter, autoclave is still the answer. Three independent variables — temperature, pressure, vacuum — under closed-loop control, with full PVT logging on every cycle.
Pressure consolidates plies. Vacuum removes voids. Temperature cures the resin.压力夯实层间。真空消除气孔。温度固化树脂
A good cure cycle does all three at the right time. Too much pressure before the resin softens and you crush the laminate; too little and you trap air. Cure too fast and you exotherm the part; cure too slow and you overrun schedule. The cure cycle is part of the design — we tune it per program against the resin's published cure profile and the part's thermal mass. 好的固化曲线让三个变量在正确的时刻到位。树脂软化前压力过大会压坏层合板，过小则会锁住空气。固化过快会让零件放热过度，过慢则会超出工期。固化曲线是设计的一部分——我们按项目根据树脂厂商发布的固化曲线与零件热质量进行调谐。
Two-zone heating handles the temperature uniformity problem on larger parts (different thermal masses cure at different rates if one heater is asked to manage the whole chamber). Six thermocouples per cure cycle land in the part itself — we hold the slowest spot to within 5°C of the controller setpoint.
Compression molding.模压成型
When part shape is simple and volume is high, autoclave is unnecessary. Compression molding closes a heated tool around prepreg or sheet molding compound (SMC) and cures in ten to thirty minutes — versus the four-hour autoclave cycle. Trade-off: less geometric freedom, less ability to handle complex layups. Right tool for the right part.
Five-minute cycle, production volume.五分钟节拍，量产规模
The math is straightforward. An autoclave run handles a cart of parts every four hours; a compression press cycles every ten to thirty minutes. For tactical handguards, pistol grip panels, structural panels, and flat brackets, the volume math points to compression molding before you even talk about per-part cost.
We run two compression presses — 200T and 400T — both with heated platens, servo-hydraulic close, and force-feedback control. Tooling is matched-metal hardened steel for production volume; aluminium for pilot runs. Both prepreg charges and SMC chopped-fiber compound run on the same presses with different mold sets.
Fibers, resins, cores.纤维、树脂、芯材
Fiber selects for stiffness; resin selects for service temperature and toughness; weave and orientation select for the load case. Material choice is part of the program engineering — we hold qualified prepreg supply across the grades below and bring fresh DSC and burn-off testing to first production cycles. 纤维决定刚度，树脂决定使用温度和韧性，编织方式与方向决定承载工况。材料选择是项目工程的一部分——我们持有以下牌号的合格预浸料供应，并在量产首轮带上新鲜的 DSC 和灼烧测试。

What composite parts routinely hold.复合材料件的常规精度
Composite tolerances aren't bounded by the machine accuracy that governs CNC parts — they're bounded by cure shrinkage, layup consistency, and tool fidelity. The numbers below reflect what we hold in production. Tighter dimensions are achievable post-cure with the integrated CNC trim line. 复合材料公差不像 CNC 零件那样受机床精度限制——而是由固化收缩、铺层一致性与模具复现度决定。下表反映我们在量产中可保持的指标。固化后通过集成 CNC 修边线可实现更高公差。
| Property | Production tolerance | Achievable | Notes |
|---|---|---|---|
| Thickness · monolithic cured laminate, no core | ±5% / ±0.10 mm | ±3% / ±0.05 mm | Tightens with cured ply mass control and strict bleed scheme on cure. |
| Thickness · sandwich cored panel | ±0.30 mm | ±0.15 mm | Driven by core flatness; Nomex honeycomb tighter than balsa. |
| As-cured dimensional part envelope, off the tool | ±0.5 mm | ±0.2 mm | Spring-back compensation in tool design. Tighter via post-cure CNC trim. |
| Post-cure trim CNC-machined edges & features | ±0.10 mm | ±0.025 mm | PCD-tooled CNC, dust-extracted. Effectively the CNC tolerance budget. |
| Fiber volume fraction prepreg autoclave parts | 55 – 60 % | 62 % | Verified by burn-off / acid digestion on witness coupons per cure. |

| Layup angle ply orientation accuracy | ±2° | ±1° | Held tighter on RFID-tagged aerospace ply kits with operator certification. |
| Tg (cure verification) witness coupon · DSC | ≥ design Tg − 5°C | ≥ design Tg | Witness coupon co-cured with each part. Lot release tied to DSC. |

Sending us a composite program.把复合材料项目交给我们
Composites are an engineered material, not a stock commodity — the layup is the design. We treat the layup schedule as part of the review, whether the customer brings one or asks us to develop one. DFM, prototype, qualification, production — the gates roll over weeks, not days, but each one is real. 复合材料是工程化的材料，不是货架商品——铺层方案就是设计。无论客户已有铺层方案还是要我们开发，铺层方案都纳入我们的评审范围。DFM、原型、认证、量产——每个阶段以周为单位推进，而非以天为单位，但每一关都是实实在在的。
Composite-specific DFM review.复合材料专属DFM评审
Sharp internal corners, abrupt thickness transitions, no-draft pockets, ply-drop staircases that aren't gradual enough — every one of these shows up later as voids, delamination, or warpage. DFM happens before tool design starts, with the layup schedule on the table.
Quote turn-around runs seven to ten business days for new programs (it includes a layup review, tool concept, and cure-cycle proposal). Prototype lead time is typically two to three weeks once tooling is ready. Production cycle depends on technology — autoclave parts run on 4–6 hour cure cycles, compression on minutes.
