Nylon 6 molding
Nylon 6 Properties
- Nylon 6 fibres are tough, possessing high tensile strength, as well as elasticity and lustre. They are wrinkle-proof and highly resistant to abrasion and chemicals such as acids and alkalis. The fibres can absorb up to 2.4% of water, although this lowers tensile strength.
Nylon 6 Molding Parts Application
- Nylon 6 is used in automotive industry parts and instruments, home appliance, electronic product cover and housing, plastic tube, kichenware parts and gears etc. It can also be used in gun frames, such as those used by Glock, which are made with a composite of Nylon 6 and other polymers.
Specific gravity: PA6-1.14 grams / cubic centimeter ，PA66-1.15grams / cubic centimeter ，PA1010-1.05grams / cubic centimeter .
Injection mold shrinkage: PA6-0.8-2.5%、PA66-1.5-2.2%
Injection molding temperature: 220-300℃
Drying material: 100-110℃ , 12 hours
Material properties: tenacity, abrasion resistance, oil resistance, water resistance, enzyme and bacteria-resistant , but absorbent is big; nylon 6 with good elasticity, high impact strength, water absorption; nylon 66 is superior to nylon 6, high strength, good wear resistance; Nylon 610 is similar as nylon 66 but the small water absorption, low stiffness; Nylon 1010 is translucent nylon with water absorption and good resistance to cold.
Nylon 6 molding performance:
- Crystalline materials, high melting point and narrow melting temperature range, poor thermal stability, if melt temperature is over 300 degrees and PA stay in injection molding barrel more than 30 min, it will be decomposed. Easy to absorb water, need to dry before injection molding, the moisture content shall not exceed 0.3% on injection molding.
- Good fluidity, easy to flash
- Nylon molding shrinkage is distinct, easy to have shrinkage cavity and deformation.
What kind of steel can be used for core and cavity of nylon 6 molding mould
- P20, P20HH, H13, H11, S7
