| Precision Electrical Parts | +/- 0.05 mm to +/- 0.2 mm |
| Complex Electrical Parts | +/- 0.3 mm to +/- 0.8 mm |
- *Formioo accommodates part lengths of up to 48", depending on the process. For larger dimensions, please reach out to us for inquiries. The tolerances listed represent minimums under ideal conditions; however, looser tolerances may be necessary based on the process, material selection, or part geometry.
Electrical Injection Molding Materials
pp
PP is particularly suited for Electrical Injection Molding due to its chemical resistance, low weight, and cost. Its high flow properties enable the production of light and tough components. PP has extensive applications in switch bases and sensor enclosures and hence is used extensively in electric mass-produced components.
• Mill Lead Time: Up to 3 days
• Color: Natural white, customizable
ABS
ABS is ideal for Electrical Injection Molding because of its excellent mechanical properties, impact resistance, and smooth flow. It allows for precise molding of complex shapes and is widely used for electronic housings and control panel components. For example, many consumer electronics enclosures are produced using ABS for its strength and detail retention.
• Mill Lead Time: Up to 3 days
• Color: Black, neutral matte finish
PC
Polycarbonate is the choice for Electrical Injection Molding because of its higher impact strength, clarity, and thermal resistance. It is best for the manufacture of transparent LED enclosures, protective screens, and instrument panels where function and looks are a requirement. Its heat resistance makes it a reliable option in harsh applications.
• Mill Lead Time: Up to 3 days
• Color: Transparent, custom options
PA
Nylon offers great wear resistance, low friction, and chemical stability and therefore is a resilient choice for Electrical Injection Molding. It is used extensively for production of connectors, gear housing, and cable management components where toughness and steady performance under stress are required.
• Mill Lead Time: Up to 3 days
• Color: Natural, customizable
PEEK
PEEK is a high-temperature performance polymer that exhibits excellent thermal stability, chemical resistance, and strength. In Electrical Injection Molding, PEEK is used in mission-critical aerospace and medical device parts needing high reliability and accuracy in extreme environments.
• Mill Lead Time: Up to 5 days
• Color: Natural, off-white, or custom
PEI
PEI is also widely renowned for its superior flame retardancy, dielectric insulation, and heat resistance. Its toughness makes it an excellent selection for high-voltage connectors, circuit breaker enclosures, and other heavy-duty electrical devices in which performance and reliability are prime considerations.
• Mill Lead Time: Up to 5 days
• Color: Natural amber, customizable
