Materials for precision injection molding
Boerjing processes PA66, PA46, POM, PEEK, PC, ABS and TPU. We review the material alongside the part design, tooling, assembly and operating conditions.
Engineering plastics we process
Start with the material family, then define the grade and requirements for your component.
Use this family overview to start the material discussion. Final selection depends on the grade, reinforcement, conditioning, component geometry and operating conditions; performance is assessed against the agreed test requirements.
Scroll horizontally to view all material selection details.
| Material family | Selection focus | What to discuss |
|---|---|---|
| PA66Polyamide 66 | Mechanical strength and stiffness, with unfilled and reinforced grades for different requirements. Material guide |
Specify the grade, reinforcement, conditioning state, assembly fit and operating environment. |
| PA46Polyamide 46 | A material family to evaluate when elevated-temperature stiffness and wear or friction behavior matter. Material guide |
Describe temperature over time, mating surfaces, lubrication and the required reinforcement or wear modification. |
| POMPolyoxymethylene / acetal | Sliding and friction behavior are key considerations when reviewing POM for moving interfaces. Material guide |
Specify the grade, mating material, movement, clearances and contact with fluids or cleaning agents. |
| PEEKPolyether ether ketone | Evaluated for combinations of thermal, chemical and mechanical demands. Grade and filler selection remain application-specific. Material guide |
Provide the exact grade, filler, exposure conditions, mating parts and dimensional acceptance criteria. |
| PCPolycarbonate | Review impact, appearance and transparency requirements together with the component geometry. |
Specify the grade, color or optical requirements, assembly stresses and contact chemicals. |
| ABSAcrylonitrile butadiene styrene | Review appearance, fit and mechanical requirements as part of the molded-part specification. |
Specify the grade, color, surface finish, assembly method and inspection requirements. |
| TPUThermoplastic polyurethane | Grade selection balances flexibility, damping and wear requirements for the intended component. Material guide |
Specify hardness, deformation and recovery requirements, contact media and service conditions. |

| PA66-GF15 | 15% glass-fibre-reinforced polyamide 66 |
| PA66-GF25 | 25% glass-fibre-reinforced polyamide 66 |
| PA66-GF30 | 30% glass-fibre-reinforced polyamide 66 |
| PA46 | Unreinforced polyamide 46 |
| PA46-GF15 | 15% glass-fibre-reinforced polyamide 46 |
| PA46-GF25 | 25% glass-fibre-reinforced polyamide 46 |

Typical raw-material property ranges
| Property | PA66 | PA46 |
|---|---|---|
| Densityg/cm³ | 1.13–1.36 | 1.18–1.41 |
| Tensile stress, dryMPa | 85–190 | 100–210 |
| Tensile modulus, dryGPa | 3.0–10.0 | 3.3–10.0 |
| Melting point, DSC°C | ≈260 | ≈295 |
| Heat deflection temperature°C · 1.8 MPa | 75–250 | 190–290 |
Ranges summarise the example resin grades below for initial material selection. Finished-part performance is reviewed for the selected grade and application. Tensile stress uses dry yield or break values. Continuous operating temperature is assessed separately for the grade and conditions.
Reference grades and manufacturer data
A material used in our cage range
PA66-GF25 · K811 and K812 cages
K811 and K812 cages use PA66 reinforced with 25% glass fiber. We review the resin grade, operating conditions and acceptance requirements for each project.
For polyurethane seals, specify the material system, grade, hardness and manufacturing requirements.
Define the part before selecting the grade
An existing material specification is a useful starting point. If the grade is open, share the application and acceptance requirements so we can discuss the molding approach.
- Material specification
- Resin supplier and grade, technical data sheet (TDS), reinforcement or filler, color and any required material documentation.
- Operating conditions
- Temperature and duration, movement and load conditions, lubrication, moisture and contact with chemicals or cleaning agents.
- Part and assembly
- 2D drawings, 3D files or approved samples; mating parts, critical dimensions, fit, appearance and estimated quantities.
- Validation requirements
- Agreed inspection methods, sample acceptance criteria, functional tests and packaging requirements.
From material review to sample approval
Material and part requirements inform tooling and molding review. We support mold trials, sample approval, small-batch validation and repeat production against the agreed specification.
