Injection molding.注塑成型
Eighteen presses spanning 50 to 650 tonnes, paired with an in-house tooling design and build group, scientific-molding process control on every press, and integrated 2K multi-shot and insert-overmold capability. Programs run from prototype tools through six-figure annual production volumes. 十八台 50 到 650 吨的注塑机，配套内部模具设计与制造团队、每台机均配备科学注塑工艺控制、双色注塑与嵌件包胶能力。项目覆盖从原型模具到六位数年产量的量产。
Eighteen presses across the tonnage range.十八台注塑机覆盖全吨位区间
Press fleet split across micro, mid-tonnage, and structural bands, plus a dedicated 2K rotary press. Auxiliary equipment — material drying, hot-runner controllers, take-out automation — sized to keep every press running with consistent shot-to-shot conditions. 注塑机分微型、中型与结构件吨位段，外加专用双色旋转盘机。辅机配置——材料干燥、热流道控制器、取件自动化——按需配套，保证每台机运行时射出条件稳定。
In-house tool design and build.内部模具设计与制造
The mold is the program. A well-designed tool runs for a million cycles with 20-second changeover; a marginal one will erode margin every shift. We design molds, machine them in the same complex, and try them out on the press they will run on — not at a partner shop two cities away. 模具就是项目本身。设计精良的模具能跑百万周期、20 秒换模；勉强可用的模具每个班次都在蚕食利润。我们自主设计模具、在同一厂区加工，并在最终生产用的注塑机上试模——不是在隔壁城市的合作工厂。
Design, machining, try-out — all in the same complex.设计、加工、试模——全部在同一厂区
A mold built off-site comes back without visibility into its build process: the design choices, the steel pedigree, the fit of the slides — none of it visible. When the part runs hot and warps a thou, you cannot fix it without another shipping cycle. When we build the tool, the mold designer is two doors from the press, and the first try-out happens on the press where the tool will live. 外部加工的模具回来时无法看到制造过程：设计选择、钢材来源、滑块配合——都不可见。一旦零件发热、翘曲一丝，没有再发一轮货就无法修。我们自建模具时，模具设计师离注塑机两个门远，首次试模就在该模具未来运行的机台上完成。
The tool room runs five CNC mills, two wire EDMs, a sinker EDM, a jig grinder, and a dedicated mold polishing bench. Steel comes in as P20, H13, S136, NAK80, or 420SS depending on volume, abrasiveness, and the optical-grade requirements of the part. Polishing goes from textured (VDI / Mold-Tech) through SPI A-1 mirror. 工模车间配备五台 CNC 铣床、两台慢走丝、一台火花机、一台坐标磨、一张专用模具抛光台。钢材按产量、磨损性、光学级要求选用 P20、H13、S136、NAK80 或 420SS。抛光等级从纹理（VDI / Mold-Tech）一直到 SPI A-1 镜面。
Scientific molding.科学注塑
We define molding processes by polymer behavior, not by recipes. Filling, packing, cooling, and ejection are decoupled and tuned independently against the data the resin is actually telling us — not against operator habit. The process gets locked, documented, and held under SPC for the life of the program. 我们以聚合物行为定义注塑工艺，而不是按"配方"。填充、保压、冷却、顶出各自解耦，分别按树脂真实数据调校——不是按操作员习惯。工艺一经锁定即归档，项目全周期内由 SPC 监控保持。
The process is defined by the polymer, not the press.工艺由聚合物定义，不由设备决定
Traditional molding tunes a single screw-forward profile and lives with the trade-offs. Scientific (decoupled) molding splits the cycle into independent stages: fill the cavity at the velocity the polymer wants, switch to packing at a known fill volume, hold pack pressure long enough for gate freeze, then cool to ejection temperature. Each stage is governed by physics, not by stopwatch. 传统注塑调一个螺杆前进曲线，然后接受随之而来的取舍。科学注塑（解耦注塑）将周期拆成独立阶段：以材料喜欢的速度填充型腔，在已知填充体积切到保压，保压时间足够让浇口冷凝，再冷却到顶出温度。每个阶段由物理规律决定，不是凭秒表。
The result is dimensional repeatability that holds across temperature shifts, humidity changes, and material lot variation. Operators do not need to "tweak" between shifts — the process is robust enough to hold spec without intervention. When something does drift, the SPC chart sees it before the dimensional inspection does. 其结果是：在温度波动、湿度变化、材料批次差异下，尺寸重复性都保持稳定。班次之间不需要"调机"——工艺足够稳健，不需干预即可保持规格。一旦有漂移，SPC 控制图比尺寸检验更先看到。
2K multi-shot & insert overmolding.双色多组分与嵌件包胶
Two rotary-platen 2K presses for hard-soft and color-on-color combinations in a single cycle, plus insert-molding capability across the rest of the fleet for metal threaded inserts, pre-machined cores, and electronic substrates. 两台旋转盘双色注塑机，单周期完成软硬或双色组合；其余注塑机均具备嵌件注塑能力，可放入金属螺纹嵌件、预加工型芯、电子基板。
Two materials, one cycle, one bond.两种材料，一次循环，一次结合
Hard-soft overmolds (a polycarbonate housing with a TPE grip surface, a PA66 frame with a silicone seal) require either a secondary bonding operation or 2K molding. Bonding adds cost, alignment risk, and a potential failure surface. 2K eliminates all three — the second shot flows onto the first while the first is still warm enough to chemically bond, producing a single-piece part with no joint. 硬软包胶（PC 外壳加 TPE 握把、PA66 框架加硅胶密封）要么走二次粘接，要么走双色注塑。粘接增加成本、对位风险、潜在失效面。双色注塑同时消除这三点——第二次注塑流到仍有余温的第一次注塑件上，化学键合形成无接缝的整体件。
Insert overmolding is a related technique: a metal insert (threaded brass insert, pre-machined aluminium core, electrical contact) is placed in the cavity, and resin flows around it. Used widely on tactical gear, optics housings, and consumer electronics where a plastic body needs metal threads or thermal pathways.
Prototyping before tooling.开模前原型试制
A mold is a fifty-thousand- to five-hundred-thousand-dollar commitment. We run an in-house additive cell — SLA, MJF, FDM — so design intent gets validated in the customer's hand before steel gets cut. Ergonomics, fit, snap-fit clearances, lens windows, button feel — all verified against a part that prints in 24 hours. 一副模具是五万到五十万美元的投入。我们设有内部 3D 打印车间——SLA、MJF、FDM——让设计意图在客户手中先得到验证，再切钢。人机工学、装配关系、卡扣间隙、镜片窗口、按键手感——全部对照 24 小时打印出的样件验证。
From CAD to handheld in 24 hours.从CAD到手持原型，24小时
The most expensive design change is the one made after a tool is cut. We see it routinely — a customer commits to steel, the first shots come off the press, and somebody's grip doesn't feel right, or two parts of the assembly don't quite mate, or a wall is thin where it ought to be ribbed. Three-thousand-dollar fix in CAD. Eighty-thousand-dollar fix once the tool is cut. 最贵的设计变更是模具切完之后再发现的。我们经常见到——客户承诺切钢，首批样品下来，握把手感不对、装配件配合不严、本应加筋的壁却很薄。CAD 阶段改三千美元。模具切完再改要八万美元。
The prototyping bay exists to catch those issues at CAD-fix cost. On most new programs we print three to five iterations before the tooling design is locked. Customers receive parts they can hold, assemble, and field-test — typically within a week of first submitting their files, often within 48 hours. 原型工位的作用就是把这些问题截留在 CAD 阶段成本内解决。大多数新项目在模具设计锁定前会打印三到五次迭代。客户收到可以握、可装配、可外场测试的实物件——通常在首次提交文件后一周内交付，常见 48 小时内交付。

What is routinely held — and what isn't.常规可达——以及不可达的精度
Injection molding tolerances are governed by polymer shrinkage, tool steel, and process control — not by machine accuracy alone. The numbers below reflect production-grade DIN 16742 zones we hold confidently. Tighter is achievable with steel, gate, and process choices made with that intent. 注塑公差由聚合物收缩、模具钢、工艺控制共同决定，不是仅靠机台精度。下方数据反映我们有信心保持的量产级DIN 16742公差等级。如有意识地选择钢材、浇口、工艺，可达到更严公差。
| Feature | Production tolerance | Achievable | Notes |
|---|---|---|---|
| Linear · unfilled commodity / engineering grades | DIN 16742 · TG 4 | TG 3 (tighter) | Tightens with steel mold (vs aluminium), longer cycle, tighter process window. |
| Linear · glass-filled PA66-GF30 / PBT-GF | DIN 16742 · TG 5 | TG 4 | Glass fillers add anisotropic shrinkage — tolerance band larger across grain direction. |
| Wall thickness consistent section | ±0.1 mm | ±0.05 mm | Cooling-balanced tool design and pack-pressure control. |
| Hole / boss diameter cored bores | +0.05 / −0.025 mm | ±0.025 mm | Reamed post-mold or hardened core pin. Tighter on smaller diameters. |
| Flatness cosmetic surface | ⏥ 0.3% / 100mm | ⏥ 0.1% / 100mm | Driven by part design symmetry as much as process. DFM review applies. |
| Surface finish SPI A through D zones | SPI B-2 / VDI 18 | SPI A-1 mirror | Mold polish controls part surface — A-1 requires hardened, finely polished steel. |

| Cosmetic class visible exterior surfaces | Class B | Class A · Show surface | Class A requires Mold-Tech texture or A-1 polish + 100% visual inspection per AQL. |

Sending us your part files.把您的零件文件发给我们
We're molders, not order-takers. The list to the right is what helps us return a meaningful quote that includes tooling cost, unit cost, and lead time. DFM happens before quoting, not after. 我们是注塑专家，不是接单员。右侧清单帮助我们给出包含模具成本、单件成本、交期的有效报价。DFM 设计审查在报价前完成，而非报价后。
What we look at on a DFM review.我们在DFM评审中关注的内容
A tool that's wrong for the part shows up later as cycle-time drag, cosmetic defects, or scrap. We look at gate location, draft, parting line, ejector placement, wall-thickness uniformity, and shrinkage compensation before steel is cut — and feed back what we'd change before quoting.
Quote turn-around runs five to seven business days for new tooling (it includes a DFM round and a mold-flow analysis). Resourcing an existing program with the customer's mold is faster — typically three to four days once the tool arrives for evaluation.
Have a part that needs tooling?有零件需要开模？
Send a 3D file, a drawing, or just describe the part and the volume. A molding engineer comes back with DFM notes, a tooling and per-unit estimate, and an honest read on whether we're the right shop for the program.
