Custom Cast Aluminum Heating Plates

• Adopts tubular heating elements as heat source, formed by precision bending and centrifugal casting with high-quality aluminum alloy
• Precision machined surface ensures tight fit with the heated object, with surface load of 2.5–4.5 W/cm²
• Maximum working temperature ranges from 300℃ to 450℃, with uniform heat distribution across the plate
• High thermal conductivity alloy eliminates hot spots and cold spots on the heating surface
• With insulation device on the outer surface and infrared sintering on the inner surface, it can save up to 35% electricity

1. Working voltage shall not exceed 10% of the rated value; relative air humidity shall not exceed 95%, no explosive or corrosive gases allowed.
2. The wiring part must be placed outside the heating and insulation layer, and the housing shall be effectively grounded. Avoid contact with corrosive, explosive media and moisture. Lead wires shall withstand long-term temperature and heating load; do not over-tighten the terminal screws.
3. Store the heater in a dry place. If the insulation resistance drops below 1MΩ after long-term storage, bake it in an oven at around 200℃ for 5–6 hours to restore normal performance, or power on at reduced voltage until insulation resistance recovers.
4. Fix the heater properly, and the effective heating area must be closely fitted with the heated body. Dry heating is strictly prohibited. Clean dust or contaminants on the surface in time to avoid affecting heat dissipation and shortening service life.
5. The magnesium oxide powder at the outlet end shall be protected from pollutants and moisture infiltration in the use site to prevent electric leakage accidents.

• Customers shall provide product drawings or samples. If no drawings or samples are available, please specify product specifications, model, voltage and power.
• Recommended surface power load for cast aluminum heating plate: 2.5 ~ 4.0 W/cm².
• All products can be customized according to your requirements. We accept drawings, voltage, power and size specifications, and can also design drawings for you according to your application needs.

Process: Uses Cr20Ni80 resistance wire as heating element, natural or artificial powdered mica sheet as insulation layer, wound and assembled with stainless steel, iron or copper sheet as outer heat conductor. Can be made into ring, plate and various special-shaped products.

Features: Light weight with fast temperature rise.

Applications: Widely used in injection molding, extrusion and other mechanical heating industries.
