Injection molding is an industrial technique that is used for producing spare parts from thermoplastic materials. The raw materials in this manufacturing process are mixed and heated in a large barrel. The ingredients are then forced into a mold cavity to get the final product. The product is usually conceived by an industrial engineer and molds are made either from aluminum or steel by the tool maker. Injection molding is frequently used by mechanical industries to fabricate a wide range of parts including car body panels, wire spools, automotive dashboards, musical instruments, bottle caps, furniture, storage containers and plastic products.

Cartridge heaters are fabricated from premium materials and can provide superior durability and high performance even under extreme temperatures. Heat Tech Systems supply both low watt density and high watt density heaters with durable stranded flexible leads that offer greater reliability and higher wattage per square inch. The cartridge heaters come with a compact refractory insulation and an even heat profile for faster heat transfers. The robust lead terminals, distributed wattage options, built-in thermocouples, swaged construction, welded end disc seals, and the numerous watt density options makes it a great product for industrial applications like plastic industry, packaging industry, hot runner bushings, sealing machinery, and shoe making industry.

Go for stainless steel cartridge heaters instead of aluminum. They are more resistant to oxidation and corrosion. A sheath watt density between 160W – 200W with a nominal bore would be more than sufficient. The heater specifications like overall length, lead type, heater size, voltage, diameter, wattage, and additional performance options like moisture resistance and temperature resistance are required before you can order one. Almost all heaters can be modified to fit custom applications. Injection molding offers many advantages including high production rates, low operation costs, reduced scrap losses, low labor costs, and it is a perfect choice for both small scale industries and factories.
