Plastic Electric Heater Shell Mould

How can the mould meet the temperature resistance and flame retardancy requirements of the electric heater?

The Plastic Electric Heater Shell Mould is specifically designed for components such as the front shell, rear cover, and side grilles of electric heaters. It is compatible with engineering resins like temperature-resistant HIPS, flame-retardant ABS, and PC/ABS, and can stably inject V-0 grade flame-retardant materials and recycled material ratios. By using materials such as flame-retardant PP, it can withstand the high temperatures of the electric heater, comply with fire safety standards, and balance safety and chemical stability. It is not prone to aging over the long term.

How to overcome the forming defects of the electric heater shell?

To address the processing difficulties of the shell's large-area thin walls, complex curved surfaces, and dense ventilation slots, the injection port position and holding pressure curve were optimized through Moldflow simulation, effectively suppressing problems such as warping, weld marks, and glue deficiency. The surface of the cavity can be subjected to high-gloss polishing (Ra ≤ 0.025 μm), texture etching, or matte sandblasting as needed, to meet various appearance requirements.

How can the mold achieve a balance between dimensional accuracy and production capacity?

The Plastic Electric Heater Shell Mould adopts materials with low linear expansion coefficient and low shrinkage rate to ensure the precise size of the shell after molding, meeting the precise assembly requirements of the electric heater. It is equipped with a standard 1×2 cavity layout and can be customized with 1×4 or multi-layer stacked molds to adapt to different production line cycle rates. The mould body is made of high-quality materials such as P20H/718, with a service life of up to 500,000 to 1,000,000 cycles, and the monthly supply capacity is 50 sets.

What are the standardized guarantees in the mold opening and delivery process?

Support for 3D and 2D drawing customization, cold runner and hot runner can be selected as needed, and reverse engineering for mold opening is also available even with only a sample provided. Each set of molds undergoes 72-hour continuous trial production to ensure that they can be put into mass production upon arrival. The minimum order quantity for an order is 1 set, it is packed in standard wooden boxes, and it will be delivered within 45-60 working days. Payment methods supported include L/C and T/T.

How can the drawing format be adapted to meet customer needs in terms of technical alignment?

The 3D format is compatible with mainstream types such as CATPart, sldprt, and step, while the 2D format supports formats like dwg, dxf, and pdf, adapting to different customer design habits. Quotations must provide 2D or 3D digital files, and the technical team can provide full alignment and optimization throughout the process to ensure that the mold design precisely matches the customer's production requirements, thereby reducing the cost of trial and error.
