Thane-based Gala Precision Engineering is a one-stop solutions provider when it comes to de-burring, finishing, washing and cleaning of machinery parts and components. It offers the whole gamut of systems and services for carrying out the said operations.
Gala’s Automatic Multi-stage Ultrasonic Cleaning Machine is a workhorse designed for precision cleaning of engine parts, shock absorbers, clutch housings, aluminium die castings, transmission parts and manifolds. It features spray, ultrasonic and immersed flood processes enabling multiple washing and rinsing operations. Its pre-programmed, automatic material handling system facilitates higher productivity due to simultaneous handling of multiple baskets. The gradual step-down type multi-stage filtration and contamination separation mechanism ensures that filtered fresh cleaning medium is available for every cycle, leading to consistent cleaning quality. On the other hand, the basket rotation mechanism ensures maximum exposure of component surfaces to washing, rising and drying processes.
Case Studies Galore
Gala has come up with interesting case studies. One case study pertains to Multi-stage Ultrasonic Cleaning of a shock absorber part which was contaminated by buffing dust. Hitherto the customer was adopting manual cleaning. The solution Gala offered was 2-stage ultrasonic cleaning with on-line filtration. The cleaning media used was aqueous, alkaline. And the cleaning was done in two stages. The first stage was ultrasonic cleaning and the second stage involved hot dip rinsing. The operation helped in increasing productivity and reducing labour cost for the customer.
In another case study, Gala describes the solution it provided for removal of buffing dust from swash plate. The input component was contaminated with water-based coolant and loose burr. Gala used a Single piece flow ultrasonic cleaning using aqueous and alkali. The cleaning was carried out in four stages. In the first stage it used ultrasonic cleaning. This was followed by spray rinsing, air blow-off and finally hot air blow-off. The entire operation was done without manual intervention. The result was consistent cleaning and 70% reduction in labour cost.
The 3rd case study is on cleaning of clutch hub with the input contamination of loose burr. The client was using batch washing to make the surface free from loose burr. Here Gala used conveyorised spray washing using aqueous, alkaline media. The machine followed the following four stages: spray washing, spraying rinsing, air blow-off and hot air blow-off. It resulted in the following advantages: single piece flow, no manual intervention, and reduced labour cost.
The fourth case study related to precision cleaning of engine housing. The input contamination was oil and loose burr. The client wanted gravimetric value of less than 2 mg and particle size of less than 600 micron. In this case, Gala resorted to Multi-chamber, Multi-Process Ultrasonic cleaning. As in the earlier case, the cleaning media were aqueous, alkaline. The cleaning process involved three stages: spray + ultrasonic + immersed flood; spry + immersed flood; and hot air blow-off. The result achieved was high productivity and consistent cleaning quality.
Cleaning Chemicals
Gala has some 10 types of chemicals for cleaning aluminium die casting parts involving different applications such as degreasing, de-scaling, cleaning oil and other contaminants, achieving bright surface finish of components, etc. It also offers high performance de-rusting, degreasing & finishing compounds and media which can achieve a Millipore value less than 1 mg particle size as per class A, and Ra value improvement up to 0.5 micron.
