The Developments in China

Fabrication is the gathering of several processes to realise a final product. These processes are long established while others are newer in origin. Each individual process enjoys further development to improve quality, throughput and yield.

Taking a look at the high complexity range of the spectrum, CNC (Computer Numerically Controlled) machines are widely applied for metal cutting. Improvement and development at this level involve the minimisation of operator interference during machine set-up and programming as well as speeding up the process time.

This in turn is done by improving cutting tool technology and enabling machines to carry out multiple operations. This has lead to an increased number of cutting tools and axes of movement being adopted.

Within the metal forming and metal joining sector, fabrication and metal folding also benefits from developments of computer control. Machines used for metal folding are becoming more and more flexible because of the expansion of computer control and clever tooling systems that permit rapid changeovers.

The metal joining sector enjoys continuous developments in welding focussing on the range of materials that can be joined as well as the delivery of the welding process. While robotic welding is becoming prevalent, very little development in the range of welding processes available, has taken place.

The staples remain as gas, arc, MIG, TIG, spot welding and variants thereof (stud welding, seam welding etc.), but the stability of these processes are great cause for confidence in its users. Chinese manufacturers deploy all these processes and has done so for many years.

Other joining processes – such as riveting and similar processes – do undergo continues development. Developments in this arena focusses on both the ease of use as well as the reliability.

In some cases, fastenings have been developed to offer dual functionality, providing threaded anchor points being a great example. This in turns minimises the requirements for further processes and components, thus reducing complexity, time and cost.

Fabrication being a term to categorise various processes, the metal fabrication industry in China takes advantage of the developments made in each of the many specialisms they deploy. A knowledgeable selection of the correct partner (or partners) will ensure that any manufacturing project undertaken benefits from the appropriate key developments.

The Processes in China

Today, in China, there is a full spectrum of fabrication providers that are able to deliver the following specialisms in various different combinations:

  • Punching
  • Welding
  • English Wheeling
  • Casting
  • Brazing
  • Extrusion
  • Heat Treatment
  • Forging
  • Oven Soldering
  • Drawing
  • Spinning
  • Painting
  • Plastic Fabrication
  • Fastening (such as riveting etc.)
  • Powder Coating
  • Shearing
  • Product Assembly
  • Powder Metallurgy
  • Cutting (such as laser cutting, sawing, guillotining etc.)
  • Machining (such as milling, turning, drilling etc.)

China also offers higher-level specialisations, including:

  • Sub-contract manufacturing
  • Prototyping
  • Machine Design
  • Technical Drawing

High skilled in managing the complex needs of clients, companies and agencies in China are able to service clients that require either some or all of these processes, be it domestic or overseas.
