FOR TOTAL SATISFACTION

SHELL CORE PROCESS

This process is standard in most foundries and allows for the formation of awkward internal passages and undercut areas. We use this process to accommodate any designs which cannot be formed by using steel cores or loose pieces.

OTHER

Many other processes are applied to assure you of the part and quality you require. Internal Heat Treat capabilities, CNC machining, traditional machining, pressure testing along with checking fixtures, Poka-Yoke, and CMM measurements round out our range of capabilities.

"QUALITY SOLUTIONS" FOR TOTAL SATISFACTION

Our commitment to quality is demonstrated by our certification as an IS09001 manufacturer of aluminum castings. To achieve this prestigious certification, we have maintained and lived up to the strict benchmarks in our industry. We are also certified with all of our major customers to the A+ level and/or preferred status. Plans are in place as we pursue QS9000 registration to better service our customers.

ASSURANCE, ACCURACY AND PRECISION

Through continual monitoring, testing, measuring and auditing, we can assure our customers defect-free products. Our methods ensure dimensional accuracy, metallurgical properties, fit

and function, SPC, process monitoring and detection of casting deficiencies. Each of our measurements is carried out using not only the traditional hand tools, gauges and

calipers, but also using computerized programs in our CMM. Coupled with accurate detailed process control plans, check sheets and our well-informed people, we maximize the quality levels to our customers.

QUALITY MEANS ON-TIME-DELIVERY

Last but not least, the objective of Grenville Castings Limited is to provide accurate, on-time delivery. Our commitment is to work with you to constantly provide what you want, when you want it - right the first time.

FOR EFFICIENT PRODUCTION

PERFE C TIN G T HE PR OCESS:

Grenville Castings Limited has been perfecting our casting processes for more than 50 years. During that time, we have tried and proved many methods of producing and processing castings. We have developed several techniques:

• Low Pressure molding • Shell Core for internal passages • Air and water-cooling in the molds • Computerized cut-off saws • Cellular on-line production

• Permanent Mold • Reusable steel cores • Cast-in inserts to eliminate machining • CNC machining • Heat Treat

We can provide the right combination to provide you a solution to your casting requirements.

CELLULA R PR ODUCT I O N :

We are committed to manufacturing using cellular production. Through this discipline, we produce the highest quality castings, with the shortest possible lead-times, at a cost-

effective level. At each step of the process - from molding to finished part, molten aluminum to packaged product - the quality of your casting is our Number One priority. Cellular production allows for immediate detection of quality-related issues, reduces lead-time, provides optimum quality checks, and applies our highly trained

specialists on your product with true ownership and responsibility for each job.

L O W PRE SS URE M O L D IN G PR OCESS :

Since 1967, Grenville Castings Limited has been involved with the Low Pressure molding process. This computer controlled process produces consistent high-quality castings. The process delivers lower cost-per-part with yields as high as 99% of melted aluminum and reduced secondary processing as a result of minimal gating. Improvements to working conditions enhances operator awareness of the process and quality because they are not exposed to the traditional molten aluminum environment.

PE RM A N E NT M OLDING PROCESS:

Our expertise allows us to tailor each process for each specific requirement. In some instances, it is necessary to use Permanent Mold due to the configuration of the product. This process is valid being ideal for thin, flat parts with large surface areas, non-symmetrical parts, and parts with critical finish requirements.
