From master pattern to production-like parts

We take your master pattern from design review and pattern preparation through silicone molding, casting, finishing, inspection, and final part delivery.

01
Design & Pattern Review
Preparing the master

We review part geometry, wall thickness, parting lines, undercuts, and mold requirements before preparing the master pattern.

Vacuum casting materials

Choose the right polyurethane resin based on strength, flexibility, heat resistance, appearance, surface finish, and the requirements of the final application.

ABS-Like

General-purpose functional resin

A versatile polyurethane resin designed to replicate the look and functional behavior of injection-molded ABS parts.

Tensile Strength≈ 40 to 65 MPa
Density≈ 1.05 to 1.20 g/cm³
Ideal ForHousings, enclosures, consumer products, functional prototypes

PC-Like

Rigid and impact-resistant resin

A rigid polyurethane material used when higher stiffness, impact resistance, and engineering performance are required.

Tensile Strength≈ 50 to 70 MPa
Density≈ 1.10 to 1.25 g/cm³
Ideal ForAutomotive, industrial, housings, mechanical components

PP-Like

Flexible and lightweight resin

A polyurethane resin designed to replicate the flexibility and low-density characteristics of polypropylene parts.

Tensile Strength≈ 15 to 30 MPa
Density≈ 0.95 to 1.10 g/cm³
Ideal ForLiving hinges, flexible covers, containers, consumer products

Rubber-Like

Flexible and elastic resin

A soft polyurethane material for parts requiring rubber-like flexibility, compression, and impact absorption.

Hardness≈ 40A to 90A Shore
Density≈ 1.00 to 1.20 g/cm³
Ideal ForSeals, gaskets, grips, flexible components

Clear

Transparent appearance resin

A transparent polyurethane material used for visual prototypes and parts where internal features or appearance need to be evaluated.

Tensile Strength≈ 40 to 60 MPa
Density≈ 1.05 to 1.20 g/cm³
Ideal ForTransparent housings, lenses, light guides, appearance models

High-Temp

Heat-resistant functional resin

Designed for functional prototypes and testing applications where higher temperature resistance is required.

Tensile Strength≈ 40 to 70 MPa
Density≈ 1.10 to 1.30 g/cm³
Ideal ForHeat fixtures, automotive, engineering prototypes, functional testing

What vacuum casting delivers

Vacuum casting combines high-quality surface finish, production-like materials, complex geometry, and low-volume manufacturing to produce functional and appearance-accurate parts.

01

Production-Like

Material Performance

Vacuum casting can replicate different material characteristics, including ABS-like, PP-like, clear, flexible, and high-temperature resin options.

02

High

Surface Quality

Vacuum casting produces smooth, detailed parts with a finish that closely replicates the appearance of injection-molded components.

03

Complex

Geometry Capability

Silicone molds can reproduce detailed features, undercuts, ribs, housings, enclosures, and other complex product geometries.

04

High

Part Repeatability

A single master pattern can be used to produce multiple consistent parts for testing, assembly validation, demonstration, and pre-production.

05

Low to Medium

Production Volumes

Vacuum casting is well suited to prototypes, functional validation, presentation models, and low-volume production before injection molding.

06

Low

Cost Per Part At Scale

Vacuum casting provides a practical low-volume alternative to hard tooling when a limited number of production-like parts are required.

Typical values shown are general industry guidelines. Actual results may vary depending on resin selection, master pattern quality, mold design, part geometry, mold life, and casting conditions.

Every finish has a purpose.

Vacuum cast parts can be finished to replicate production-like appearance, custom colors, smooth surfaces, or protective coatings. The right finish depends on the resin, master pattern, and final application.

Cadlete Designs helped me design a 3d model for a quite complex project: the Lightsaber. There were a lot of design decisions which mattered here, and they executed them perfectly! After 3d printing everything worked out well and connected well. The response time is phenomenal, after asking for fixes they were done the next day or even sometimes the same day. They also provided nice explanation videos each time to explain the design choices made. Would definitely recommend!
