Custom Rapid Prototyping from Concept to Low Volume Parts

HC-Mold supports product designers, R&D engineers, start-ups and purchasing teams with custom rapid prototype manufacturing. Our services include SLA, SLS and MJF 3D printing, CNC machining, vacuum casting with silicone molds and low-volume production. We help create appearance models, engineering test parts, functional assemblies and market validation samples before tooling or mass production.

Why Engineers Choose Our Rapid Prototype Service

Practical manufacturing support for product development, testing and market validation.

Rapid Prototyping Capabilities

Prototype Materials for Different Test Requirements

Material selection affects strength, flexibility, transparency, heat resistance, surface quality and cost. Final availability and suitability are confirmed after reviewing the drawing and application.

Note: ABS-like, PP-like, PC-like, TPE-like and TPR-like vacuum casting materials simulate selected properties. They are not necessarily identical to injection-molded production plastics.

Choose the Right Prototype Process

We recommend the process after reviewing geometry, mechanical needs, appearance and quantity.

SLS and MJF Functional Prototypes

SLS Selective Laser Sintering and MJF Multi Jet Fusion are suitable for durable PA nylon parts, clips, housings, ducts, lattices and functional assemblies. Because no support structures are required, these processes can produce complex internal features and nested geometries efficiently.

SLA Appearance Models

SLA Stereolithography is ideal for fine details, smooth surfaces, clear models, presentation samples and painted appearance verification. It is often selected when visual quality and dimensional detail are more important than long-term production material performance.

CNC Machining and Vacuum Casting

CNC machining uses real engineering plastics and metals for accurate functional prototypes, threads, mating features and mechanical testing. It is suitable when material behavior or tighter critical dimensions matter.

Vacuum casting with silicone molds, also called urethane casting or silicone mold casting, supports consistent low-volume parts in varied colors, transparency and hardness. It is useful for design verification, customer samples and bridge quantities before injection molding.

Prototype Applications & Custom Options

Supporting early concepts, engineering validation, functional testing, exhibition samples and low-volume launch parts for automotive, robotics, medical devices, consumer electronics, industrial equipment and new product development.

Manufacturing & Quality Support

One project team coordinates DFM review, production, dimensional inspection, finishing and delivery for clearer communication. Inspection can include calipers, micrometers, height gauges, CMM measurement and project-specific reports when agreed in the quotation.

Replace bracketed data only with verified company information and valid certification scope.

A Clear Path from File to Delivery

Simple milestones help reduce uncertainty and keep your development schedule visible.

1. Send 3D/2D files and requirements > 2. DFM and quotation > 3. Confirm order > 4. Production updates > 5. Inspection > 6. Secure packing and delivery

Service Assurance

- DFM review can identify wall thickness, tolerance, thread, assembly and finishing risks before production

- Dimensional inspection is arranged according to confirmed drawings and critical requirements

- Protective packaging selected for part geometry and finish

- Any issue is reviewed against the approved file, specification and inspection record
