Custom Rotational Molding Plastic Housings and Other Parts for Robotic Equipment

Robotic equipment requires robust housings or covers to protect various sensitive electrical and mechanical components against rain, wind, water and sunlight. Rotational molding is the ideal molding process to create rugged and durable plastic housings and covers for robotic equipment application. Unlike the metal, roto molded plastic housings are lightweight, free of rust, and they don’t corrode easily. The material choice is recyclable polyethylene because of its excellent impact and chemical resistant characteristics.

Rotational molding process

Rotational molding, also known as rotomolding, is a process most commonly recognized for its ability to easily manufacture large hollow parts. A hollow mold is loaded with a predetermined amount of material, then slowly rotated while being heated, causing the melting material to evenly distribute to the inside surface of the mold. The mold continues to rotate throughout the heating phase, as well as the subsequent cooling phase. Finally, a seamless hollow part is then removed from the mold and the process is repeated again.

Benefits of roto molded polyethylene housings for robotic machine

1. Low production cost

In comparison to other molding processes, the mold cost is relatively low. For the same products, the mold cost about 10% to 20% of the injection mold. Little material is wasted in the production. The color, logo, texture, graphics, metal threads, inserts can be molded in. The process allows for undercuts and multiple walls. This saves both time and money.

2. Design freedom

Rotational molding offer design flexibility that a variety of shapes and size can be molded, ranging from small to oversize, simple to complex geometry.

3. High quality level

• One-piece construction. free of joints and welds, leakage free
• Size can be precisely controlled with roto molding
• Airtight and watertight to protect the inner component against the moisture, dust, rain and other elements
• Polyethylene is light weight, dent and fracture resistant,
• Shock and vibration resistant
• Anti-static/conductive and anti-microbial/bacterial by adding addictive
• Material can be tailored made with flame retardant, UV stability
• Easy maintenance
