Material for Spinning
Most material can be formed using one spinning process or another. At Autoform CC we have spun exotic materials such as silver, gold, Zirconium etc.
When selecting the best material for your project, some of the factors that have to be taken into consideration are:
» Is the required grade of material readily available in South Africa?
» What are the different material thicknesses that can be purchased?
» Does the material work-harden, which would then require additional annealing to achieve the final shape?
» Does the material require heating during the spinning process?
Mild Steel
Many simple shapes can be successfully spun from mild steel. The metal spinning process gives additional strength to the mild steel material. Beads and grooves can strengthen a mild steel product significantly. Mild steel products can be further finished off with powder coating, annealing or plating.
DDQ - Deep Drawing Quality Steel
This is Autoform CC’s most common material used for spinning products. It is a steel that is more pliable than mild steel and the product does not work-harden which makes it the ideal steel for complex shapes and large production runs.
Autoform CC has the ability to work with material from 0.7mm to 10mm thickness when spinning DDQ. Our blank sizes can range up to 1.2 metres in diameter.
DDQ is a higher-grade material than mild steel and the scrap rates are reduced significantly. DDQ is a premium material and costs approximately 13% more than mild steel. This is normally offset by the low scrap rate which Autoform CC achieves.
Some of the DDQ products which we spin are tank ends, nozzles, cones, venturis, light fittings, etc, to name a few.
Aluminium
The grade of Aluminium that we mainly get in South Africa is 1050 H4. We have found this material to be suitable for our spinning processes on the automated spinning machines. We are able to achieve tight tolerances in the forming of nose cones for the aeronautical / military industry and just as easily get a good product on the lighting reflectors that we make. We have many years of experience spinning the High Bay Reflectors from Baisch Engineering, which was the leader in South Africa from the 1960s to 2000. It was then that Autoform CC entered the spinning market and picked up where Baisch left off.
Aluminum is light in weight, cost effective and resistant to corrosion which makes it the ideal material for many spinning products. We spin from 0.7mm to 12mm aluminium. We can spin blanks from a diameter of 150mm to 1.2 metres.
Stainless Steel
Autoform CC mainly uses 304 and 316 grade stainless steel. 304 Stainless has slightly less nickel than 316 and this makes it less resistant to corrosion. It is also the cheaper of the two materials.
We use 316 Stainless for products in the medical, hospitality, military and laboratory industries.
304 is used as a decorative material, used in the creation of balustrade caps/ends, lighting, chimney flues, drinking cups and ash trays to name a few.
We are able to form certain simple shapes with a combination of spin forming and sheer forming. More complex shapes require an annealing process as the material work-hardens relatively quickly. There can be a number of annealing processes involved in the spinning process of just one part. This has a direct impact on the price and the lead time of the production process.
The development process of stainless-steel items is a bit longer and thus more lead time must be planned into spinning a new product.
