Case Studies

One of the biggest problems the customer encountered during manufacturing was their previous coolant left a sticky residue on the tubes. The fluid also created substantial foam during operation, contributing to low-quality surface finishes for their parts. The additional cleaning and reworking significantly reduced throughput and labor efficiency.

Additionally, the sticky residue and foam caused the machines, dies, and rollers to get dirty and accumulate contaminants, requiring special cleaning that further reduced production output. The foam, along with a short sump life, led to frequent fluid changes, driving up fluid costs.

The customer transitioned to WEDOLiT FW 7652^®, a specialty fluid best suited for wire drawing and forming welded stainless steel tubes. In addition to providing superior lubrication and forming ability, FW 7652 offers significant corrosion protection, even at a concentration of four to six percent. The product’s excellent thermal stability allows it to be used throughout the production process, including initial forming, highheat welding, calibrating, and sawing.

WEDOLiT FW 7652 produces no foam and keeps workpieces and machines clean throughout the manufacturing process. After switching to the new product, surface finish for completed parts immediately improved. Machine operators also reported a better shop environment due to less odor, and significantly improved tramp oil rejection over their previous product.

Another advantage is WEDOLiT FW 7652 features a robust formulation and excellent sump life, even without additional tank side additives. Combined with a lower carry-off rate, the new WEDOLiT formula has allowed the customer to lower their fluid usage from 35 liters per month down to 20, a 42 percent decrease.
