Manufacturing Vacuum Cast Plastic Parts Robotics Nylon PA66 PEEK Joints Housing Units

In the robotics industry, components must be lightweight, durable, and capable of withstanding repetitive movement and heavy loads. Vacuum casting is an increasingly popular method for producing plastic parts used in robotics, as it allows for the creation of precise and high-performance components that meet the demanding requirements of this industry.

Nylon PA66 is known for its excellent strength, stiffness, and wear resistance, making it ideal for components like robotic joints, gears, and housings that experience frequent friction and mechanical stress. It is also lightweight and can be easily molded into complex shapes, making it suitable for creating intricate parts that fit into tight spaces.

PEEK, on the other hand, is a high-performance material that excels in extreme conditions. It is resistant to high temperatures, chemicals, and wear, which makes it perfect for critical robotic components such as joints, connectors, and housing units that must operate reliably in harsh environments.

The vacuum casting process begins with a master model, which could be a 3D-printed prototype or an existing part. This master is used to create a silicone mold, which captures all the fine details of the design. Liquid resin, such as Nylon PA66 or PEEK, is injected into the mold under vacuum pressure, ensuring that the resin fills every part of the mold and results in parts with smooth surfaces and precise dimensions.

The use of vacuum casting for robotics allows manufacturers to quickly produce prototypes and low-volume production parts. This is particularly useful for developing new robotic systems or testing out different design iterations.

• Cost-effective production of high quality, low volume plastic parts similar to injection molding
• Ideal for form, fit and function tests during design stages
• Suitable for marketing, field user testing and product design verification
• Wide range of material options to satisfy different design requirements
• Capable of producing fully opaque, translucent or completely transparent parts
• Can create high-quality wax masters for investment casting

Polyurethane (PU) is a polymer material with excellent mechanical properties and plasticity. It can be classified into several types including polyether-type, polyester-type, polyimide-type, and polyurea-type, with applications ranging from foams to fibers, rubbers, and elastomers.

Flexible polyurethane has better stability, chemical resistance, resilience and mechanical properties than PVC foams, making it ideal for packaging, sound insulation and filtration materials.

Rigid polyurethane is lightweight with superior thermal insulation performance, mainly used in construction, automotive, and aviation industries.

Polyurethane elastomers offer performance between plastic and rubber, with excellent oil resistance, abrasion resistance, and elasticity, primarily used in the shoe and medical industries.
