In the field of bending, Refco does not shy away from any challenge. We also supply small series or complex products. Refco uses European mandrel bending machines that can process tubes up to a diameter of 108 mm. Even the largest pipe sizes can be bent with a radius of 1,2 times the pipe diameter. This ensures compact constructions that do not require fittings for brazing. In addition, Refco als rolls pipes into rings and into single or multiple spirals. You can get an overview of our standard bending tools on request.

For right-angled branches on a pipe, a T-piece can be chosen. However, Refco can drill holes with a raised collar, making a T-piece unnecessary. For this application, Refco processes pipes with diameters between 12 mm and 108mm.

The possibilities in term of hole diameter, degree of rotation and workpiece length are virtually unlimited. The collar forming process can also be used for the production of very complex manifolds.

For larger series, we use an automatic collaring machine.

To close a tube end, the customer can opt to give a semi-spherical shape to the tube. This is done by placing the tube in a rotating die. This process is called spinning and is less labour-intensive than other end forms. A spun workpiece can withstand a higher internal pressure.

To finish off a tube end, customers can opt for end-plate brasing. Besides this technique and spinning, sawn tubes can also be given another end-forming treatment:

• Reduce diameter
• Expand diameter
• Create joints

Brazing or hard soldering is the technique of using a gas burner to locally raise the temperature of the workpieces above 600°C. Afterwards, the liquefied filler material is allowed to flow in to create the joint.

Refco has a large team of specialised operators who braze on a daily basis. They join:

Refco is the reference in manufacturing parts and assembling parts into semi-finished products that you can further build into machines or appliances. We make the jigs required for precision work ourselves. You benefit from high product quality without having to have this specialisation in-house.

At your request, we put together total packages consisting of manufactured workpieces and small parts. This lowers your stock levels and reduces your administration and logistics.
 

Refco not only processes copper, but can also carry out most workpieces in stainless steel or aluminum, metal-reinforced copper for CO2 applications, ... Our team is ready to guide you in the process for tailor-made products from our customers in a wide range of businesses.

Refco is also your partner for smal series welding in stainless steel or steel.
