Promolding

Transforming high-performance polymer technologyinto sustainable industrialized applications

Some of our customers

Mission:


• Rapid Prototyping (1988) • SLA (Stereo Lithography), • LOM (paper), • FDM (Fused deposition modeling),• etc.

• Rapid Tooling (additive tooling)• Starting with Stereo Lithography molds• Later additive technologies with metal

• Rapid manufacturing (additive manufacturing)• Very promising• Small range of materials

History of 3D printing


Validation of the design at an early stage is critical for success

Major influence

Low influence

Decreasing influence


• Additive manufacturing:• Successful in manufacturing small series of parts• New way of engineering products (has yet to be

discovered)• Scaling up to large series is economically often not

justified• Limited amount of materials

• Additive metal tooling:• Still expensive• Needs finishing

Current options

Focus: To bridge the gap from single prototypes in prototyping materials to injection molded production series in final material

Goal: Better validation of the design before critical investments

Using: 3D printing of molds and injection molding knowhow

A process called PRIMPRinted Injection Molding

Materials

Shrinkage comparable to regular injection molding.

Continuously testing new materials


• Mold buildup• No ejector pins• No specific mold cooling• No slides

• Product complexity• Mold can be composed of multiple inserts (undercut possible)• Manual operation

• Part geometry• Draft angles 3 degrees or more• No sharp corners minimum radius 0,5

Boundary conditions


• High level validation of design in early development stage

• Large range of functional materials available

• Short lead-time (approximately 5 days)

• Low costs (depending on design €2500 - €5000)

Advantages of PRIM


Information on http://www.promolding.nl/en/prim-en/

In 2017:

A new company (P3D) specialized in PRIM will be started.

PRIM will have a full automated website to estimate mold and product costs

Stratasys will release a new molding material Q2 2017
