Precision Manufacturing for Robotics Industry

Robotics is a diverse, relatively new industry, but most prominent in the industrial and manufacturing sectors. Applications here include robotic arms, collaborative robots (aka cobots), robotic process automation, integrated artificial intelligence (AI), predictive maintenance, and service robots. For components created for the robotics industry, dimensional accuracy is vital. Parts are complex and must be precise to work in sync with other components assembled within a robot. Surviving the stresses of repeatable actions is also essential. Other key considerations include customizability, low-friction surface finishes and complex geometries. And that's why digital manufacturing is uniquely valuable in the production and assembly of parts for the robotics industry.

3D Printing in the Robotics Industry

3D printing is increasingly being used in the robotics industry due to its ability to produce organic, complex, and efficient additive parts. It offers endless possibilities regarding geometries that may not be possible with machining or molding and has a broad material selection of plastics and metals. Additive manufacturing also allows for multi-part assemblies to be combined into a single design, saving production dollars.

CNC Machining in the Robotics Industry

CNC machining is an ideal service for robotics development due to precision and dimensional accuracy as well as material selections. Machined parts have tighter tolerances than other services, and 5-axis CNC milling can produce highly complex parts, important for applications that demand precise, repeatable movements. During post-processing, machining allows for controlled surface finishes, which are needed for low-friction components in interactive parts. Machining is perfect for customized robotics components in low quantities.

Injection Molding in the Robotics Industry

Injection molding offers a repeatable option when low- to mid-volume production is required. Piece-part price will often be reduced as quantities increase with our volume pricing model. It's not the primary manufacturing process used for producing robotic components, it is commonly used for production of housings, frames, and casings, for example. Liquid silicone rubber (LSR) molding is also becoming increasingly common with the introduction of soft robotics.

What Materials Work Best for the Robotics Industry?

Aluminum

expand_less expand_more

A popular choice for the robotics industry due to its lightweighting capabilities. Certain alloys also display corrosion resistance, good weldability, and high heat resistance, all important properties to have for applications in the robotics industry. For those alloys that don't offer great corrosion resistance, further treatments such as anodizing can be used to improve resistance.

There are also good surface finish options for aluminum to enhance cosmetics for on-display robots, for example. It also has the added benefit that is machinability.

Stainless Steel

expand_less expand_more

A common material used by those in the robotics industry. Stainless steel is a solid choice for components on robotic applications that need to be durable and survive repeatable processes and harsh conditions.

Stainless steel can also be hardened easily, which can be useful when using it in the framework or body of a robot, for example. It is the ideal material for parts that need to combine corrosion resistance with high strength and temperature resistance.

Acetal/Delrin

expand_less expand_more

Acetal (aka Delrin) is a common plastic robotics. It is light weight so it can be a good alternative for lightweighting applications. Acetal boasts excellent dimensional stability and has low friction, both critical characteristics for robotic components that may be sliding or performing repeatable actions. And it's relatively inexpensive compared to other common materials used in the industry.

Elastomeric Materials

expand_less expand_more

Elastomers are becoming increasingly popular in the robotics industry due to the rise of soft robotics, which are used for more delicate tasks that require a less heavy hand. These materials are also used for internal components in standard robots, such as semiconductors and casings where flex is needed.
