Plastic Materials for Every Application
Selecting the right material is essential to achieving the performance, durability, and appearance your application requires. CSI Keyboards works with a variety of engineering plastics to support custom molded housings, enclosures, and integrated HMI assemblies.
Injection Molded Plastic Advantages:
- The plastic injection molding process is a fully automated process to realize high production efficiency.
- The plastic injection molding process makes it possible to produce detailed or complicated parts. The moment a part is manufactured via the plastic injection molding process, there would be little finishing work needing to be done, because the produced parts look extremely finished.
- Availability of a wide range of materials in the plastic injection molding process, or mix different materials for a combined outcome (co-molding).
- Very little waste will be produced in the injection molding process, because excessive materials are able to be easily recycled.
- Mold inserts can be used to produce a new or modified part (through this process, you can change the internal cavity without complete redesigning or re-machining of the steel or aluminum tools by CNC).
Common Plastic Materials Include:
Nylon (PA) – Strength, toughness, and wear resistance
ABS – Impact resistance and excellent surface finish
Polypropylene (PP) – Lightweight construction and chemical resistance
Polyethylene (PE) – Durability and moisture resistance
Polyphenylene Oxide (PPO) – Dimensional stability and thermal performance
Polyester Resins – Mechanical strength and electrical insulation
Polycarbonate (PC) & Acrylic (PMMA) – Impact resistance or optical clarity, depending on material selection
The Advantages of Plastic Injection Molding
Plastic injection molding offers an efficient, versatile manufacturing solution for custom interface components and enclosures.
Efficient Production: Repeatable manufacturing processes support consistent quality and scalable production volumes.
Complex Design Capabilities: Create detailed geometries, mounting features, and integrated components with precision.
Material Versatility: Select from a wide range of engineered plastics to meet specific mechanical, environmental, and aesthetic requirements.
Reduced Secondary Operations: Near-net-shape molding can minimize additional machining and finishing.
Material Efficiency: Controlled processes and appropriate material recovery practices can help reduce manufacturing waste.
Design Flexibility: Interchangeable mold inserts can support certain design modifications without requiring completely new tooling.
