A Shanghai-based prototype manufacturer covering CNC plastic/metal precision prototypes, 3D printing, vacuum casting small batches, and full finishing: spray painting, sandblasting, laser engraving, silk screening and assembly. Free DFM review — send us your drawings for a quote.
A Shanghai-based prototype manufacturer since 2009 — one seamless flow from single prototypes to batch orders.
Shanghai Hengfu Model Co., Ltd. ("Hengfu") was founded in 2009, headquartered at No. 268 Fangtai Park Road, Anting Town, Jiading District, Shanghai, with production bases in Shanghai, Sichuan and Jiangsu. We are a machining service provider focused on product prototyping, precision parts manufacturing, model making and batch order delivery.
Core capabilities cover CNC plastic prototypes, precision metal prototypes (aluminum, stainless steel and other metals), 3D printed prototypes, sheet-metal parts and mold-based volume production, plus a complete finishing line: spray painting, sandblasting, plastic spraying, anodizing/electroplating, laser engraving, silk screening and assembly. Besides single-piece prototyping, we accept small, medium and large batch orders (CNC small batches, vacuum-cast trial runs, mold-based volume production) — one seamless flow from prototype validation to mass production.
Our factory runs 50+ CNC machining centers (with 4-axis and 5-axis simultaneous machining) backed by an experienced programming and process team. We specialize in rapid prototyping and precision model machining for mid-to-high-end R&D products: laptops, tablets, phones, automotive, robotics, smart eyewear and smart terminals. We machine plastic parts, sheet-metal parts, die-cast and cold-forged tooling, precision hardware and gear transmission parts; we excel in thin-wall and complex internal-cavity parts (extremely rich experience in laptop and automotive structural components) and in precision mold-modeling for stationery, small appliances and telecom products. Machining precision up to ±0.05mm.
Machinable materials include engineering plastics — ABS, PBT, PP, PC, POM, PA (Nylon) — plus aluminum, stainless steel, magnesium-lithium alloy and special alloys. We support DFM manufacturability review to flag structural risks before mold-making and shorten validation cycles, as well as sample testing and dimensional inspection.

From a single prototype to batch orders — four core capabilities cover the whole product development flow.
CNC plastic & metal precision prototypes in aluminum, copper, steel, titanium, Mg-Li alloy and special alloys. Multi machining centers, precision ±0.05mm.
Fast validation of form, fit and complex internal cavities — see the result first, then decide on the process.
Vacuum casting for small-batch trial runs, mold-based production for volume. CNC small batches and casting both supported — from validation to delivery in one step.
Grinding → sandblasting → spray painting → laser engraving → silk screening → assembly — full one-stop responsibility with quality control throughout, delivered as finished parts.
Three process routes, matched to your validation stage — spend only on what you need.
Multiple CNC machining centers with an experienced programming & process team, skilled in thin-wall and complex internal-cavity parts. Standard precision ±0.05mm.
Best for validating form, fit and complex internal cavities — fast and low-cost for 1-5 pieces.
Low-pressure vacuum casting for small-batch trial runs; mold-based production for volume. CNC small batches also available — one seamless flow.
Full coverage of engineering plastics and metals, with a complete finishing line for production-like quality.
Metal parts: natural/black anodizing, sandblasted oxidation, brushing, laser-engraved logos — full one-stop responsibility with quality control throughout.
Five capabilities beyond the drawing — what sets us apart from ordinary machine shops.
Manufacturability analysis before production — spot structural risks before mold-making, shorten validation cycles. Free evaluation.
Thin-wall (0.5-0.8mm) and complex internal-cavity parts are our specialty — multi-pass machining with proper support for stable dimensions.
Grinding → sandblasting → spray painting → laser engraving → silk screening → assembly — full one-stop responsibility with quality control throughout, delivered as finished parts.
Single prototypes and small-to-medium batch orders (CNC / vacuum casting) both accepted — no need to switch suppliers midway.
Customer samples tested and dimensionally inspected before ordering — verify capability first, both sides stay confident.
Authorized cases from delivered projects (material/process per production records).
Compound, fine-tooth and custom gears machined in one setup with consistent tooth quality and matte finish — ideal for transmission validation.
Multiple bores, bosses and flange ears machined in one part with matte anodized surface — a clean structural part for electronic/instrument mounting.
Bottom, palm-rest and lid covers delivered as a set — vent mesh, keyboard and trackpad openings cut in one pass, production-like metal finish.
Red/black design with vent mesh, cable routes and mounting bosses machined in one part — high assembly precision.
Complex housing assembled with metal shafts; clips and connector ports fully formed — demonstrating plastic-plus-metal assembly capability.
Frame available in both metal and plastic — and more than just frames: the complete eyewear structure in one piece. Thin-wall frames machined without deformation, symmetrical hinge bosses, matte finish — proof of stable thin-structure machining.
