How to get a fast, accurate injection molding quote

Got a deadline approaching? Need a fast, accurate quote without the back-and-forth?

To provide fast, accurate quotes, we need a few key pieces of information up front—no guesswork, no surprises.

We put together a quick guide for design engineers and sourcing teams to help streamline the quoting process and set your project up for success.


1

3D CAD Data
(.STP format)

3D models allow us to assess moldability, parting lines, undercuts, and draft. We use them to develop accurate tooling and part cost estimates.

What to include:

STP File
Final Design Version


2

2D Drawings of all parts & Assemblies

Even with 3D models, 2D drawings often contain key tolerances, finishes and other important callouts not captured in the CAD files.

What to include:

Critical Dimensions
Surface Finishes
Tolerances


3

Material Specification

Material choice impacts mold design, cycle time, shrinkage, and tooling wear. It also informs gate design and cooling strategies.

What to include:

Resin Name & Grade
Any Additives? (e.g. glass fill)
Compliance Needs
Can a substitute be used?


4

Estimated Annual Volume

Knowing how many parts you need helps us select the right mold class, cavitation, and tooling approach—so you don’t overpay or under build.

What to include:

Target Volume per Year
Ramp-up or Phase-in Schedule


5

Quality & Validation requirements

Regulated industries like medical or aerospace may need IQ/OQ/PQ, PPAP, or Cpk studies. These affect cost, lead time, and mold design.

What to include:

Applicable Standards or Protocols
Specific Documentation or Testing Needed


6

Cleanroom molding needed?

Cleanroom requirements impact machine allocation, handling, packaging, and compliance costs. We need to plan accordingly from the start.

What to include:

Cleanroom Class
Post Mold Packaging Needs
