HMAC USA Reduces Marginal Blasting Costs by 33% with W Abrasives HPG

HMAC USA is a automotive casting facility located in Lawrenceville, Pennsylvania, with a manufacturing/machining location in Wellsboro, Pennsylvania and an additional manufacturing/machining plant in Effingham, Illinois. They specialize in Ductile Iron castings, precision machining and assembly for the OEM automotive industry. HMAC’s product mix consists of safety suspension components, and brackets. HMAC’s customer base includes Ford, Chrysler, General Motors, BMW, Mazda, Nissan, Subaru, Mitsubishi, Honda, VW and others.

Although HMAC was not experiencing any operational challenges within the blasting phase of their operations, W Abrasives introduced a new and innovative solution to improve the process. With total confidence in the product HPG and the technical support provided by W Abrasives, HMAC’s blasting operation team along with the W Abrasive technical team went ahead with the HPG 6 trial in one of HMAC’s Disa blasting machines. The results were exceptional.

HMAC experienced a 33% reduction in marginal blasting costs reaching tens of thousands of dollars in
savings. The categories in which savings were realized are abrasives, common costs, management, manpower maintenance, spare parts, wear parts, and energy. One significant indicator of total overall improved blasting was the ability to continue with more efficiency
while blasting with only five wheels and shutting down the other two wheels in their seven wheel blasting machine. In addition to the shut down of these two wheels, the life of each blasting wheels were able to be extended by one week.

“HMAC is an industry leader in providing ductile iron safety critical castings to the Automotive market, our relationship with W Abrasives has enhanced that position. W Abrasives unequaled technical support and superior product selection delivers the unique customer/supplier relationship that all manufacturers strive to establish in this intensely competitive environment”.
Robert Harter VP Mfg.

HPG is just one of the solutions W Abrasives has introduced in its line up of premium products, designed to reduce the overall cost of blasting operations. HPG, high performance grit, is specially designed to improve shot blasting performance in the foundry industry. It works faster, it lasts longer, and its capacity for removing contaminants and cleaning are unequalled.

HPG is a total package product that includes technical expertise to support all blasting operations with W Abrasive customers. The premium product HPG is supported by W Abrasives technical experts that will analyze the conditions of the machine, the operating mix, the efficiency of the process, the results achieved, and the total cost of the operation. This technical support is part of the premium package offered ‘Free of Charge’ by W Abrasives and one example of how W Abrasives is leading the industry in blasting efficiency through innovation and providing solutions to their customers.

Following the trial of HPG 6, HMAC has fully converted one blasting machine to this operating mix and is in the process of introducing HPG into its second blasting machine. W Abrasives would like to thank the employees at the HMAC Lawrenceville plant and the W Abrasive employees that helped to put together another successful trial with W Abrasive products.

Winoa : The Best Abrasive Blasting Solutions Provider

This Premium product has been specially developed for foundry application of materials. This approach was not so easy. Blasting molded parts requires large quantities of grit. Obviously, the customer wants to reduce their blasting times and also cut cost while making no compromise with quality.

The Premium concept and HPG range has been successfully introduced in the two most important foundries in the USA.
This approach has been led by Craig Wallbank, a key member of the WALUE team of the Group Winoa.
