What Can You Validate
Before Production?

Rapid prototyping helps your team check key design risks before tooling or mass production.

Validate structure, PCB fit, assembly method, and basic product function before moving forward.

Prototype assembly and testing with PCB and plastic enclosure

Prototype Assembly & Testing

For checking how all parts work together as a final product.

  • PCB, enclosure, wiring assembly
  • Fit and handling review
  • Basic function checks
  • Feedback before production

Vacuum Casting

Vacuum casting uses a silicone mold under vacuum to cast polyurethane or ABS-like resins. It is ideal for low-volume prototype production and can closely replicate injection-molded parts.

Prototypes can be delivered within 5–7 days, suitable for low-volume production from 10 to 100 pcs.

Applications:

  • Plastic enclosures for electronics and consumer products
  • Transparent or colored resin components
  • Assembly verification and functional testing

Key Benefits:

High fidelity

Replicates injection-molded surface finish and detail.

$
Cost-effective runs

No need for expensive steel molds.

Post-processing ready

Compatible with painting, plating, and silk-screen printing.

From Prototype to Production

A prototype is only valuable when it leads to the right manufacturing decision.
CINDY MOULD helps you move from sample review to tooling, assembly, and production
with less risk, fewer changes, and a smoother path to market.

01

Prototype
Review

Evaluate design, fit, and function with prototype samples.

Prototype review for PCB and enclosure validation
  • Review structure, PCB fit, and appearance
  • Check basic function and assembly feasibility
  • Identify issues before tooling investment
02

Design Adjustment

Improve the design based on prototype feedback.

Design adjustment for enclosure prototype structure
  • Optimize enclosure details and internal space
  • Adjust PCB position, connectors, or wiring
  • Confirm changes before the next sample or tooling
03

Tooling &
Production Decision

Decide whether the product is ready for mold making or trial production.

Tooling and production decision before mold making
  • Confirm final structure and manufacturing direction
  • Prepare for injection mold making or low-volume runs
  • Reduce modification risks after tooling starts
04

Production
Preparation

Move from validated prototype to assembly and shipment planning.

Production preparation for product assembly and testing
  • Plan PCB assembly, product assembly, and testing
  • Review packaging and delivery requirements
  • Prepare a smoother path to mass production
Reduce Risks

Find and fix issues early to avoid costly changes.

Improve Accuracy

Optimize design for better fit and function.

Save Time

Streamline the path to tooling and production.

Increase Confidence

Make decisions with real samples and data.

More than prototyping. We help you build a reliable path from idea to market.

What We Need to Start Your Prototype

The more complete your project information is, the faster we can evaluate the prototype method, cost, lead time, and production feasibility.

Send Us Your Project Details

You do not need to have everything finalized before contacting us. Our team can review your files, drawings, samples, or requirements and suggest the most suitable prototyping direction.

Early review helps reduce repeated samples. It also helps avoid tooling changes, assembly issues, and production delays later.

Helpful for faster review:

01

Product function and application

02

Prototype quantity and target timeline

03

Files, drawings, samples, or reference photos

01 3D Files

STEP, STP, IGS, or other 3D files for enclosure, plastic parts, or product structure.

02 PCB Files

Gerber files, BOM, placement files, or PCB assembly requirements.

03 Drawings & Dimensions

2D drawings, tolerance requirements, key dimensions, and assembly notes.

04 Material Requirements
