As a national high-tech enterprise and a specialized and innovative enterprise, we leverage over 20 years of experience in large-scale automotive prototype modeling and precision component machining, along with a fleet of world-class manufacturing equipment, to provide the automotive industry with one-stop manufacturing services encompassing large body panel machining, complex functional component verification, small-batch pilot production, and large-scale mass production.
Industry Needs: Why Do Automotive Customers Need Rapid Prototyping and CNC?
Physical Verification and Assembly Matching
Before the design is finalized, full-size physical prototypes or interior/exterior trim samples are created through high-precision CNC machining or 3D printing. This allows for real-world verification of assembly interference, clearances, and fit tolerances between components, significantly reducing the substantial losses caused by later mold modifications.
Automotive-Grade Functional Testing
Using the same materials as the final production version (such as glass fiber reinforced PA6+GF30, flame-retardant PC, etc.), wind tunnel testing, high/low temperature cycling testing, combustion testing, and insulation withstand voltage testing are conducted under real-world conditions to ensure that the sample materials and performance fully meet mass production standards.
Seizing Market Opportunities
Without waiting for expensive steel molds, rapid production of exhibition parts or pre-production batches can be achieved through vacuum molding or low-pressure casting. This allows for early deployment to international auto shows, roadshows, or full-vehicle road testing, securing a valuable window of opportunity for official market launch.
Lightweight Manufacturing of Complex Structures
Facing the high demands for weight reduction and heat dissipation in new energy vehicles, we utilize metal 3D printing technology to create complex metal brackets or motor housings with conformal cooling water channels and irregularly shaped cavities in a single process, breaking through the limits of traditional machining.

Differentiated Recommended Processes
(Matching Part Characteristics)
We break away from the "one-size-fits-all" approach, providing optimal process matching based on the development stage, size requirements, and mechanical properties of different parts:
Large interior and exterior trim/coverings (>1 meter)
Preferred options are CNC machining (maximum travel 2800x1800x850mm, seamless for ultra-large sizes) or RIM low-pressure injection molding (precisely suitable for large, unevenly thick parts such as automotive bumpers, eliminating the need for steel molds, extremely low cost, and extremely short cycle time).
Complex shells, high-strength functional test parts
SLS laser powder sintering 3D printing (using PA or PA+GF materials, high temperature resistance and excellent mechanical properties, can be directly assembled and bench tested) or SLA photopolymerization 3D printing (a large-scale equipment group of 68 units, suitable for rapid appearance styling review).
Extremely complex metal structures and irregularly shaped water channels
Metal 3D printing (such as direct powder molding of aluminum alloys, titanium alloys, stainless steel, etc., breaking the limitations of traditional CNC deep hole and internal cavity machining).
Small batch samples and fine appearance parts
Vacuum casting (German-imported vacuum casting system, rich material selection, extremely high surface reproduction, multiple hardness options including ABS/PMMA/soft rubber).
Bulk metal structural parts
Batch CNC machining (suitable for large-scale precision machining of metal parts such as aluminum alloy, magnesium alloy, copper, and stainless steel, achieving milling and turning in conjunction with a CNC lathe).
Automotive-Specific Material Selection
Plastics/Resins: ABS, PC (flame retardant/transparent), PMMA, PP, POM, PA6/PA66 (nylon), PA+GF (glass fiber reinforced nylon), PPS (high temperature resistant), PU (polyurethane), photosensitive resin (ABS-like).
Metallic Materials: Aluminum alloy (AL6061/AL7075), copper, zinc alloy, magnesium alloy, stainless steel (304/316), steel, titanium alloy.

Quantitative Targets
Strictly adhering to a 100% sample pass rate, a shipment batch pass rate ≥98%, and a 100% on-time delivery rate.
Automotive Interior and Exterior Surface Finishing Capabilities
The final appearance of a car determines its market competitiveness. Our dust-free spray booth and professional after-sales workshop offer a variety of automotive-grade surface finishing solutions:
Automotive Interior Texture Finishing
Customizable leather texture paint, rubber paint (enhancing anti-slip properties and tactile feel), water transfer printing (carbon fiber texture, wood grain, peach wood grain), laser engraving (button characters and dashboard backlit icons).
Automotive Exterior Protection and Metallization
High-gloss/matte/frosted spraying, transparent component staining (for taillight or ambient lighting verification), vacuum electroplating/water electroplating/sputtering (chrome plating, silver plating, color plating, and other metallic effects, commonly used for car logos and trim strips).
Comprehensive Vehicle Finishing
We have extensive experience in comprehensive surface finishing processes for whole-vehicle models, enabling us to coordinate unified painting, multi-color painting, and high-gloss chamfering for all interior and exterior trims.
Can we transition from functional prototypes to small-batch trial production or even mass production?
Absolutely. We offer professional services with no minimum order quantity (MOQ).
Fast Delivery and Scheduling: For automotive projects with urgency, our management team dynamically coordinates resources such as 88 CNC machines, 68 SLA machines, and metal 3D printers to achieve short delivery times while ensuring quality.
Seamless Integration into Mass Production: From single-piece functional prototypes to trial production of dozens of vehicles for exhibition, and then to mold making and injection molding mass production in our in-house mold factory, the entire process can be managed by the same core technical team. This one-stop, turnkey "prototype-small-batch-mass production" model significantly reduces your cross-supplier management costs and ensures consistency in manufacturing processes and materials from R&D to mass production.
