Van Der Horst —Holland due to their innovations in advance chrome plating technologies such as its patented "Porous Krome", set up its plant in India to cater customers in South Asia. United Van Der Horst has boost its excellence in porous and hard chrome plating for different diesel engine parts and various other components of hydraulics, with due considerations to environmental safety. Components are chrome plated with hardness up to 60-65 HRC and are super finish to achieve required surface finish value. Plating process followed by United Van Der Horst has been approved by American Bureau Society (ABS) and tested at NABL approved laboratory for Salt Bath Test, Chrome peel off test, Hardness Test.

Capacity : Jobs with maximum diameter of 1 meter and length in excess to 10meters can easily be chrome plated at our plant.

At United Van Der Horst everybody is more cautious about the quality, and to get the best results in chrome plating a good amount of investment made by the management as a result of innovative suggestion by Quality control department. De-mineralized water is used in chrome plating to reduce the contamination level of chronic solution.

United Van Der Horst has always believed as an environmental friendly industry. Chrome plating fumes / effluent emerging from plating process is controlled by an in house effluent treatment plant prior to disposal, as per environmental norms. These chrome plating flumes are hazardous to health and therefore, and investment has been made in the form of high capacity blower which runs 24 hrs a day for removal of this flumes from 8 chrome plating tanks.

Like chrome fumes, disposal of liquid waster also a major issue for plant based on chrome plating. Specially designed waste handling system in conjunction with MIDC waste management department transforms the liquid waste in to solid waste before disposing. Thus preventing pollution of ground water.

United Van Der Horst has qualified team with calibrated equipments for various types of Lab tests such as chemical analysis to monitor consistency of chrome plating and chemical analysis of other ingredients which are used in the chrome plating process. We do regular routine check ups for sulphur, iron and chrome percentage present in plating solution to maintain required surface hardness.

All three bays of the plant are fully equipped with 8 EOT cranes with the capacity of up to 25 T. All consignments can be unloaded and mobilized to all the processing areas for various jobs within the plant and can be loaded directly from the dispatch section into the vehicles.

Submerged Arc Welding (SAW) - With the help of 10 ton positioner, our welding expertise find it easy for welding over wide range of products like AGC cylinder, Work roll chock, Pinion - Shaft, Bevel Gears, Pinion, Piston, Piston Head and many more components with submerged arc welding process

At United Van Der Horst, we got approved WPS (welding procedure specification) from third parties like ABS, DNV, IRS for the specific application & based on the material of composition which are tested at certified laboratory. Also our welders are 6G approved. Our welding capabilities cover the entire spectrum of welding - SMAW, SAW, TIG, MIG, etc. Our specialized welding like Aluminium Bronze cladding is approved by ABS - Houston. These processes are specifically for load / guide / bearing application and not to avoid scoring, wear & tear etc. for internal and external components such as exhaust valve spindle ad exhaust valve seat's damaged faces are weld build up using stellite weld material to provide hard and wear resistance surface. All the electrodes are baked at a temperature of 150°C to 200°C prior to welding to achieve sound welding.
