Parts cleaning

The manufacturing process inevitably leaves unwanted deposits on springs and wireform components from machining and related fabrication processes.  Parts cleaning is an integral part of Springtech’s service.

Onsite facilities

The company’s onsite facilities ensure parts and products are delivered thoroughly clean; ready for packaging, further assembly or integration into the broader product development plan.

Degreasing

Springtech finishing capabilities extend to vapour degreasing services, which can be accomplished in a number of ways including solvent vapour degreasing and acid dipping.

Springtech’s C&C hydrosonics vapour degreasing facility includes a programmable option catering for a variety of different processes including five-stage automatic system process, automatic loading facility with scrubbed air purification, immersion in liquid solvent with ultrasonic agitation, vapour immersion and a drying station.

Cleaning

Springtech is equipped to offer customers every key cleaning stage under one roof.  The type of component and end application determines the most effective process.  Typical immersion times vary between 2 and 30 minutes and temperatures dependant on chemicals used.

Quality chemicals for pristine results
Five separate cleaning tanks are employed to immerse components with the necessary chemicals required for residue-free results.

Specialist cleaning agents are kept in house that support ultrasonic, water rinse and bubble agitation cleaning processes; acid dipping; passivation and demineralised water (circulated) for the finish rinse.  Two position drying options from Springtech’s drying station equipment conclude the cleaning process and reaches temperatures up to 165ºC. 

Passivation

Some materials require specialist treatment in order to get the very best out of their composition.

For example, stainless steel requires an electrochemical passivation process, which chemically treats the metal with a mild oxidant such as a nitric acid solution.  The process removes the “free iron” contamination left behind on the surface of the stainless steel following machining/fabrication. 

Prevention and cleaning in one
These free iron contaminants create potential corrosion areas on the components and may result in the product or component deteriorating prematurely, if not removed.  Through forming a layer of a thin transparent oxide film onto the component’s surface, the passivation process leaves the part thoroughly clean. 

Cleans and protects the part’s surface
The transparent oxide film further protects the stainless steel from the threat of selective oxidisation or corrosion.  The passivation service offered by Springtech therefore offers a two-in-one benefit for stainless steel components.  This ultimately avoids unnecessary waste or extra cost to the end customer.
