Frequently Asked Questions about POM Injection Molding
Explore common questions related to POM injection molding, including its moldability, production process, applications, and recycling challenges. Get insightful answers to better understand the characteristics and uses of POM in manufacturing.
What is POM in injection molding?
POM, or Polyoxymethylene, is a high-performance engineering plastic known for its strength, low friction, and excellent dimensional stability. In injection molding, POM is used to create precision parts for applications requiring high durability, such as gears, bearings, and automotive components. Its excellent wear resistance and smooth finish make it ideal for creating long-lasting, high-quality plastic parts.
Does POM require drying?
Yes, POM (Polyoxymethylene) does require drying before injection molding. POM is hygroscopic, meaning it absorbs moisture from the air, which can affect its molding quality. Moisture can cause defects like bubbles or surface blemishes. To prevent this, POM should be dried at around 80°C (176°F) for 2-4 hours before processing to ensure optimal results and high-quality parts.
What temperature is POM molded at?
POM (Polyoxymethylene) is typically molded at a temperature range of 180°C to 220°C (356°F to 428°F). The mold temperature usually ranges from 20°C to 80°C (68°F to 176°F), depending on the part’s size and complexity. Proper temperature control ensures optimal flow, reduced shrinkage, and high-quality finished parts with precise dimensional accuracy.
What is the injection pressure for POM?
The injection pressure for POM (Polyoxymethylene) typically ranges from 800 to 1,500 bar (11,600 to 21,750 psi), depending on the part’s complexity and size. Higher injection pressure is often required for intricate or small parts to ensure the material fills the mold completely and consistently. Proper pressure control is essential for achieving high-quality, defect-free molded components.
What is the melting temperature of POM?
The melting temperature of POM (Polyoxymethylene) typically ranges from 165°C to 175°C (329°F to 347°F). This temperature range is important for achieving optimal flow during injection molding. Maintaining the correct melting temperature helps ensure smooth processing, reduces the risk of degradation, and guarantees that the molded parts have excellent mechanical properties and dimensional stability.
How much psi for injection molding?
The injection pressure for molding varies depending on the material and part design. For general injection molding, pressures typically range from 1,000 to 3,000 psi (69 to 207 bar). For engineering plastics like POM, pressures can be higher, around 1,500 to 3,000 psi (103 to 207 bar), to ensure the material fills the mold completely and achieves high-quality, precise parts.
