Domin revamps its fluid energy techniques with Renishaw’s metallic AM expertise

UK-based fluid energy techniques producer Domin has collaborated with metallic 3D printing specialist Renishaw to redevelop a few of its merchandise. Excessive-performance direct drive servo valves, used for remodeling indicators into stress, on the firm have been made smaller, cheaper and extra environment friendly utilizing the expertise. Renishaw’s metallic powder mattress fusion printer RenAM 500Q has been used to provide the redesigned rotary valve.  

The fluid energy sector

Fluid energy techniques make the most of liquids or gases beneath stress to generate and transmit power. The pressurized fluid bearing performs work instantly on a piston in a fluid motor. Then the fluid motor creates a torque which units the fluid in rotary movement. To control the system, valves are used as management parts. In comparison with mechanical or electrical drives, fluid energy techniques are extra compact, last more and permit extra exact management. Main markets for fluid energy are System 1, area, aerospace, automotive, cellular hydraulics and industrial vegetation. Domin’s new direct drive servo valve specifically serves each aerospace and industrial markets.

Additive manufacturing within the fluid energy sector

A wide range of sectors are using additive manufacturing in excessive worth, small quantity manufacturing. For instance, 3D printing software program firm Betatype used RenAM 500Q to make orthopedic implants. “Additive Manufacturing is a key expertise for Domin,” Martin McMahon, AM Lead Technical Marketing consultant at Renishaw commented. “It provides the corporate the flexibility to construct advanced components, freed from tooling and with minimal operations and meeting. Making an attempt to combine such advanced performance into such a small design wouldn’t be attainable utilizing standard manufacturing strategies.”

Launched in 2017, RenAM 500Q is a quad laser metallic additive manufacturing machine from Renishaw that builds advanced metallic parts instantly from digital CAD recordsdata. Its excessive deposition fee of most 150 cm³/hour considerably improves productiveness and lowers value per half. The machine additionally options automated powder and waste dealing with techniques to make sure constant course of high quality.

The design freedom of 3D printing has allowed Domin to engineer a brand new secure design of a direct drive servo valve. The redesigned drive is 25% extra highly effective than the unique however solely 1 / 4 of the scale. It was produced for a 3rd of the associated fee, and the cycle occasions has lowered from 5.5 hours to only one. On this sense metallic additive manufacturing additionally reinvented the connection between value and weight of fluid energy equipment. Historically, the extra materials you take away from an element, the dearer an element turns into. Now with metallic additive manufacturing, the lighter the half, the cheaper the half when put in.

Whereas weight-critical markets equivalent to aerospace and protection profit from the lowered weight, cost-critical markets equivalent to automotive and cellular hydraulics profit from the lowered prices from utilizing additive manufacturing.
