About REAC Group

REAC Group, headquartered in Helsingborg, Sweden with a major branch in Warsaw, Poland, is a global leader in actuator and motion system technologies for medical mobility devices. Their solutions are widely used in electric wheelchairs, rehabilitation systems, and patient transfer lifts — serving users across Europe and beyond.

Known for compact design, intuitive motion control, and strict quality control standards, REAC holds high expectations for every custom component integrated into their systems. Every part must meet rigorous functional and structural requirements to ensure safe, reliable performance in mobility applications.

What the REAC Team Needed

REAC Group's Poland branch approached SHBD with a clear manufacturing brief — deliver a set of precision structural components for their power wheelchair drive systems that would enhance product durability, integration, and user mobility. The engineering team required parts that met exacting specifications for fit, strength, and repeatability across production batches.

  • Custom brackets and clamps — Precision-machined aluminum components designed to integrate seamlessly with REAC's existing actuator configurations and mounting geometries.
  • Lightweight high-strength structures — CNC-machined components optimized for weight savings without compromising structural integrity in mobility applications.
  • Compatible linkages and joints — Custom-engineered interfaces fully compatible with REAC's linear actuator systems, ensuring smooth motion and reliable force transmission.
  • Fast prototyping and iteration — Rapid turnaround on prototype samples with responsive engineering feedback cycles, allowing REAC to validate fit and performance quickly.
  • Production-ready validation — All parts passed structural validation and batch assembly tests during initial sampling and pilot runs, confirming readiness for series production.

REAC's technical team expressed strong satisfaction with SHBD's delivery speed and product reliability, paving the way for further collaboration on mobility devices and rehabilitation frame support hardware.

Engineering Process

01

Design & Engineering Review

SHBD's engineering team analyzed REAC's actuator configurations and mounting requirements, developing custom aluminum bracket and clamp designs tailored to the power wheelchair drive system geometry.

02

CNC Precision Machining

All components were CNC-machined from lightweight aluminum stock with tight tolerances, achieving the high strength-to-weight ratio required for medical mobility applications.

03

Structural Validation & Assembly Testing

Every part underwent structural validation and batch assembly testing to verify fit, strength, and compatibility with REAC's linear actuator systems before shipment.

04

Delivery & Engineering Feedback

Prototypes were delivered on a fast timeline, with SHBD's team responding quickly to REAC's engineering feedback for iterative refinements. All pilot run parts passed acceptance criteria.

Technical Highlights

All structural components were CNC-machined from lightweight aluminum, delivering the optimal balance of strength and weight essential for power wheelchair drive systems. Key features:

  • High dimensional accuracy for reliable integration with REAC's actuator assemblies
  • Weight-optimized geometry reducing overall system load
  • Consistent repeatability across all pilot production batches
  • Aluminum alloy selected for corrosion resistance and long-term durability

SHBD designed and manufactured custom linkages and joints engineered for seamless compatibility with REAC's linear actuator systems. These interfaces ensured:

  • Smooth force transmission between actuator and wheelchair frame
  • Precise alignment with existing mounting points and geometries
  • Minimal play and backlash for consistent motion control
  • Robust attachment mechanisms rated for repeated cyclic loading

One of REAC's key requirements was speed. SHBD delivered prototype parts on an accelerated timeline and maintained a rapid iteration loop with REAC's engineering team:

  • Initial samples produced within days of design finalization
  • Responsive refinements based on REAC's fit and function feedback
  • Multiple revision cycles completed within aggressive project timelines
  • Fast-track communication through dedicated engineering channels

All delivered components were subjected to rigorous quality validation to meet REAC's strict standards for medical mobility components:

  • Structural validation: each part tested for strength and dimensional accuracy
  • Batch assembly tests: full-set assembly verification ensuring perfect fit across all components
  • Surface quality inspection: visual and tactile inspection meeting medical-grade expectations
  • Documentation: full inspection reports provided for each production batch

This project further demonstrates SHBD's growing capability as a trusted precision supplier to the global medical motion control sector. Our team's experience with:

  • Understanding of medical device quality requirements and regulatory expectations
  • Proven track record of delivering precision components for motion-critical applications
