Mechanical Design

Mechanical Design Services

Rayner Engineering provides mechanical design, 3D CAD modelling, engineering drafting, and manufacturing drawing services for mines, refineries, commercial clients, small businesses, fabricators, and heavy industry. We help take ideas, sketches, site measurements, or existing equipment and turn them into accurate 3D models, detailed manufacturing drawings, and practical engineered products.

Our mechanical design work is supported by strong welding engineering knowledge, International Welding Engineer (IWE) supervision, and years of practical manufacturing experience, allowing us to design components, weldments, and assemblies that can be efficiently fabricated, maintained, and commissioned.

Reverse Engineering & 3D Scanning

  • Reverse engineering of existing components for new manufacturing, repair, or analysis

  • 3D scanning and measurement of complex parts, equipment, and fabricated structures

  • Development of new designs, modifications, and repair solutions from existing equipment

  • Creation of accurate CAD models and manufacturing drawings from damaged, worn, or legacy components

Mechanical Design & Drafting

  • Mechanical design and 3D CAD modelling using Autodesk Inventor Professional

  • Manufacturing drawings for fabricated structures, weldments, sheet metal, machined components, and mechanical assemblies

  • Advanced Finite Element Analysis (FEA) and Computational Fluid Dyanamics (CFD) studies for existing and future designs, corroborated with analytical engineering calculations.

  • Concept design development from sketches, workshop ideas, site measurements, and existing parts

  • Design-for-manufacture support to reduce fabrication time, material waste, rework, and project cost

  • Steel structure design for large and small industrial structuresas per AS 4100 requirements

  • Pressure vessel design and modification support for projects involving AS 1210 requirements

  • Large weldment design supported by IWE weld engineering experience

  • Engineering documentation, design packs, fabrication drawings, and project support from concept through to finished product

Mining, Civil & Industrial Equipment Design

  • Mining and civil fleet design, including water truck bodies, service modules, dump truck modifications, and various fixed plant site equipment

  • Vehicle access system designs for trucks, mobile plant, and industrial equipment, including access, egress, ladders, stairs, platforms, handrails, and walkways, aligned with AS 5327 and AS 1657

  • Mechanical equipment modification, guarding, access improvements, and maintainability upgrades

  • Hydraulic and hydraulic-over-electric system design for mobile mining and civil equipment

  • Design support for fabrication, installation, commissioning, and site implementation

Rayner Engineering combines practical mechanical design, CAD modelling, welding expertise, reverse engineering, and manufacturing support to help clients turn ideas into reliable, buildable products. From small brackets through to large mining equipment and fabricated assemblies, we provide engineering design services that help projects run smoothly from concept to completion.
