Injection Molding for Prototypes and Low-volume Production Parts

Choose from two molding options tailored to your manufacturing needs

Injection molding can provide a range of lifetime part volumes—from as few as 10 to more than 10 million. We're a low-volume manufacturer, typically producing 10 to 10,000+ parts from aluminum molds. We provide two injection molding service options. One is best suited for those who need smaller part quantities often associated with prototyping and the other a good fit for those who require larger part quantities common in low-volume production.

Prototyping or On-demand Manufacturing?

While the molds themselves are similar, part quantities, lifetime maintenance, quality documentation, and pricing vary depending on which service option is chosen. The right one depends on your project needs.

PROTOTYPING ON-DEMAND MANUFACTURING
OBJECTIVE I need to validate my design I need the flexibility of on-demand production of end-use parts

Why Shunjing Prototyping?

  • Reduce design risks
  • Test multiple designs simultaneously
  • Accelerate speed to market

Why On-Demand Manufacturing?

  • Manage demand volatility
  • Reduce total cost of ownership
  • Leverage cost-efficient bridge tooling

Piece-Part Price Comparison

This chart shares the potential cost savings you can achieve with on-demand manufacturing for molded parts with varying levels of complexity.

PART COMPLEXITY SIMPLE MEDIUM HIGH
EXTENTS 1 in. x 1 in. x 0.65 in. 3.5 in. x 2.5 in. x 1 in. 4.2 in. x 4.2 in. x 2.9 in.
PART VOLUME 0.16 in.^3 2.73 in.^3 7.31 in.^3
PIECE-PART PRICING

PROTOTYPE
SINGLE-CAVITY MOLD

$1.50 $2.45 $7.50

ON-DEMAND MANUFACTURING SINGLE-CAVITY MOLD

$1.00 $1.70 $5.30

ON-DEMAND MANUFACTURING
MULTI-CAVITY MOLD

$0.40 $0.85 $2.00

Note that this is just an example of parts to illustrate the potential piece-part price savings offered by on-demand manufacturing.



Multi-cavity molds can provide substantial piece-part cost savings compared to single-cavity molds.

Enhanced Quality with Digital Inspections

Digital inspection reports on molded parts are available on every on-demand manufacturing order. Our metrology lab uses a 360-degree, 12-position 3D scanner that collects data, identifies dimensional variance, and creates a visual aid and color map for a direct CAD-to-scan comparison.
