Custom mold & plastic parts, Rapid tooling

Our injection molding capabilities

Our network of Manufacturing gives you easy access to diverse capabilities to serve all your manufacturing needs.

Name	Description
Rapid tooling	Molds with aluminum inserts with a life time of up to 20,000 runs. Machined in typically 2-3 weeks.
Production tooling	Traditional hard molds, machined in typically 4-5 weeks.
Single cavity molds	Molds containing only one cavity, producing one unit per run.
Molds with side-action cores	Cores slide out of the part from the side before it is ejected from the mold. This allows for undercuts to be molded.
Multi-cavity molds	Multiple identical cavities are machined into the mold tool. This allows for more parts to be produced per shot, minimizing the unit costs.
Family Molds	Several parts are designed into the same mold tool. This allows for the minimization of tooling costs.
Insert molding	Inserts are placed into the mold and molding occurs around them. This allows for inserts such as helicoils to be molded in your design.
Overmolding	Premade parts are placed into the mold to mold over them. This allows for multi-material injection molding.

Available materials for plastic injection molding

All thermoplastics can be injection molded. Some thermosets and liquid silicones are also compatible with the injection molding process.

ABS, Nylon (PA 6), PC/ABS, Polyurethane (PU), Acrylic (PMMA), Polypropylene (PP), Polystyrene (PS), Polycarbonate (PC), Polyvinyl chloride (PVC) and POM (Acetal/Delrin).

Available surface finishes for injection molding

Injection molded parts are not usually post-processed, but the mold itself can be finished to affect the surface finish of the molded part.

This way aesthetic needs or technical requirements can be achieved.

Name	SPI Standard	Description
Glossy	A-1, A-2, A-3	The mold is smoothed and then polished with a diamond buff, resulting in parts with a mirror-like finish.
Semi-gloss	B-1, B-2, B-3	The mold is smoothed with fine grit sandpaper, resulting in parts with a fine surface finish.
Matte	C-1, C-2, C-3	The mold is smoothed using fine stone powder, removing all machining marks.
Textured finish	D-1, D-2, D-3	The mold is first smoothed with fine stone powder and then sandblasted, resulting in a textured surface.
As-machined finish		The mold is finished to the machinist's discretion. Tool marks may be visible.
