Metal Assemblies Ltd recently developed a precision welded assembly combining pressed stainless steel components with CNC machined shafts, supported by investment in a new controlled heating furnace to optimise welding performance.

This project demonstrates our capability to deliver complex engineered assemblies requiring controlled manufacturing processes.

Project Overview

The assembly consists of:

• Pressed and formed 316 stainless steel bracket

• Precision CNC-machined shafts

• Machined countersink features

• High-accuracy welded joints

The stainless steel bracket is:

• Progression pressed

• Formed

• CNC machined to produce precision countersinks

These countersinks provide a precision location interface for the machined shafts prior to welding. Typical positional tolerances are maintained within micron-level limits, ensuring accurate assembly alignment.

Design for Manufacture (DFM)

During early production development, our engineering team worked to optimise the manufacturing process using Design for Manufacture (DFM) principles, focusing on:

• Joint preparation

• Material compatibility

• Heat control

• Process repeatability

This ensured consistent weld quality and dimensional stability.

Investment in Controlled Heating Technology

To support production, Metal Assemblies Ltd invested in a new industrial heating furnace supplied by a UK specialist manufacturer.

The furnace provides:

The furnace provides:

• Controlled and repeatable heating

• Stable welding conditions

• Improved process consistency

Controlled pre-heating allows the machined components to reach an optimum welding temperature, improving weld integrity and reducing process variation. This investment forms part of our ongoing commitment to continuous process improvement and product quality.

Quality Assurance

  Quality is verified through structured inspection procedures

  including:

  • Dimensional inspection

  • Process validation

  • Destructive macro testing of weld sections

  Macro examination verifies:

  • Weld penetration

  • Joint integrity

  • Process consistency Customer validation also includes advanced tomographic inspection techniques to confirm internal structural integrity.

Production Volumes

The assembly is manufactured in ongoing production volumes of several thousand units per month, supporting global supply requirements. Products are shipped internationally including:

• Europe

• South America

• Asia

Integrated Manufacturing Capability

This project demonstrates Metal Assemblies Ltd’s ability to combine:

• Presswork

• CNC machining

• Precision turning

• Controlled heating

• Welding

• Inspection into a single integrated manufacturing solution.

Engineering-Led Manufacturing

By combining engineering expertise with targeted investment, Metal Assemblies Ltd continues to develop manufacturing solutions for complex metal components and assemblies.
