Our injection molding capabilities

Our network of Manufacturing Partners 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

Common thermoplastic with high impact resistance, low-cost & low density. Vulnerable to solvents.

Injection molding plastic materials ABS

Nylon (PA 6)

Engineering thermoplastic with excellent mechanical properties and high chemical & abrasion resistance. Susceptible to moisture.

Injection molding plastic materials Nylon PA 6

PC/ABS

Blend of two thermoplastics resulting in high impact strength, excellent thermal stability, and high stiffness. Vulnerable to solvents.

Injection molding plastic materials PC ABS

Polyurethane (PU)

Thermoplastic with high impact strength and good mechanical properties & hardness. Suitable for molding parts with thick walls.

Injection molding plastic materials Polyurethane PU

Acrylic (PMMA)

UV resistant plastic with good abrasion resistance, stiffness and hardness.

Injection molding plastic materials Acrylic PMMA

Polypropylene (PP)

The most common Injection molding plastic. Excellent chemical resistance. Food-safe grades available. Not suitable for mechanical applications.

Injection molding plastic materials Polypropylene PP

Polyethylene (PE)

Lightweight thermoplastic with good impact strength & weather resistance. Suitable for outdoor applications.

Injection molding plastic materials Polyethylene PE

High density polyethylene (HDPE)

Excellent strength-to-weight ratio, impact and weather resistant.

Injection molding plastic materials High density polyethylene HDPE

Polystyrene (PS)

The Injection molding plastic with the lowest cost. Food-safe grades available. Not suitable for mechanical applications.

Injection molding plastic materials Polystyrene PS

Polycarbonate (PC)

The plastic with the highest impact strength. High thermal resistance, weather resistance & toughness. Can be colored or transparent.

Injection molding plastic materials Polycarbonate PC

Polyvinyl chloride (PVC)

Light weight plastic with good mechanical strength and abrasion resistance. Generally used in building and construction applications.

Injection molding plastic materials Polyvinyl chloride PVC

PEEK

High-performance engineering thermoplastic with excellent strength and thermal & chemical resistance. Used to replace metal parts.

Injection molding plastic materials PEEK

POM (Acetal/Delrin)

Engineering thermoplastic with high strength, stiffness & moisture resistance and self-lubricating properties. Relatively prone to warping.

Injection molding plastic materials POM Acetal Delrin

Additives and fibers

nuoue offers additives and reinforcements as options for your plastics parts.

Name Description
UV absorbers Absorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardants Prevent ignition and inhibits spread of fire.
Plasticizers Increase flexibility and promotes plasticity, reducing brittleness of the material.
Colorants Used to color plastics.
Carbon fibers Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle.
Glass fibers Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle. It is more flexible than carbon fibers.

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
Injection molding surface finishes Glossy 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.
Injection molding surface finishes Semi-gloss Semi-gloss B-1, B-2, B-3 The mold is smoothed with fine grit sandpaper, resulting in parts with a fine surface finish.
Injection molding surface finishes Matte Matte C-1, C-2, C-3 The mold is smoothed using fine stone powder, removing all machining marks.
Injection molding surface finishes Textured finish 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.
Injection molding surface finishes As-machined finish As-machined finish   The mold is finished to the machinist's discretion. Tool marks may be visible.

Injection molding design guidelines

The table below summarizes the recommended and technically feasible values for the most common features encountered in injection molding.

Learn more in our Engineering Guide to Injection molding.

Feature Recommended Description
Injection molding design guidelines Wall thickness Wall thickness Thickness: 1 mm and 3 mm To avoid warping and sinking, parts should be designed with the smallest possible and constant wall thickness.
Injection molding design guidelines Smooth transitions Smooth transitions 3 × wall thickness difference If wall thickness cannot be avoided, use a chamfer or fillet to make the transition as smooth as possible.
Injection molding design guidelines Rounded edges Rounded edges Internal edges: > 0.5 × wall thickness External edges: internal fillet + wall thickness Add a fillet with a radius that is as large as possible to all internal and external edges.
Injection molding design guidelines Draft angle Draft angle For parts taller than 50 mm: increase the draft by 1° for every 25 mm For parts with a textured finish: increase the draft by an extra 1°-2° Add a draft to all vertical walls to make the ejection of the part easier and avoid drag marks.

Design verification program for injection molding

Nuoue offers the Design Verification Program (DVP) for all injection molding orders.
Similar to First Article Inspection, our Design Verification Program allows you to receive two sets of parts for inspection and test fit before continuing with the full production run.
