Offering custom and production sterling silver and karat gold casting services.jpg (24843 bytes)  

    Our speciality is sterling silver casting. 100% of our production capacity is dedicated to client work.  We have no line of our own to compete with your designs in the marketplace.  We offer production design assistance to our clients to insure the manufacturability of a specific design component and we're glad you stopped here for a preview of our shop.  We can tell you about our company, describe the services we offer, list our professional affiliations and provide you with a brief history of metal casting.

   Our shop regularly casts mechanical, electrical and close tolerance parts for artists, jewelers and industry.  We regularly pour yellow brass, silicone bronze, and other copper alloys that are nearly as hard as some alloys of cast iron and have a very fine "as cast" surface.   In addition, we cast pure gold, various karat gold alloys, fine silver, and sterling silver.  We have assisted all sorts of clients that include medical component systems designers, industrial designers, artists, jewelers and other component system teams.

 

OUR QUALITY ADVANTAGE

    Tom, has been in the casting and precious metals industry since 1970.  We have full factory production capacity.  The production technique that we use, known as lost wax casting, allows us to replicate, in metal, hundreds or thousands of exact copies of the part you or your company needs. 

Casting to Replace Machining

    Casting can be used to form a complex, three dimensional shape, to close engineering specifications, in a much more efficient way than machining. This results in a high quality product at a lower cost. "Casting is so versatile and cost effective that it is estimated to be used in more than 90% of all manufactured goods (AMS Handbook)."  By allowing our business to handle your production needs, your business conserves its resources to focus on the areas that are most profitable for you.

Our Facility Specializes in Casting Fine Silver

    Although we cast many metals, our true market niche is working with pure silver.   Pure silver is a metal like no other. It's electrical properties are unmatched by gold and the platinum group metals and it possess antibacterial qualities that make it ideal for specific medical uses. We are presently engaged in manufacturing fine silver investment castings for electrical and medical uses.  Many casting shops that regularly pour other nonferrous metals have difficulty with the melt and casting requirements of fine silver.

Our shop can offer many other services to compliment every step of the design and production process....

Production Design Assistance

    Often designs are born mature and ready for production.  More often they can be improved with a small technical adjustment based on our experience with manufacturing countless styles in great volume. We can suggest ways to make your idea more cost effective to manufacture.

Model Creation

    Our model makers can work from your SLA file, and "old fashioned" pencil and paper three view drawing, or we can work through the design process with as little as a sketch on a restaurant napkin that includes dimensions.

Mold Making

    You can rely on our expertise to provide this important step in the manufacturing service. We will gate your model to insure the best possible results with the least expense to you. Our mold-making materials yield exact detail with absolute minimum shrinkage. We can even make molds of organic or clay models without damage to the original. We often fabricate custom mold frames to accommodate unusually large or heavy designs.

Order Fulfillment Through Casting

    We employ solid mold casting by the lost wax method. We can cast your designs using an expensive electronic induction melt gravity pour vacuum assist casting machine, through melting in a gas fired crucible furnace or torch melting and centrifugal mold filling. Let us decide the method that will provide you with the best results.

Finishing

    The degree of finish is your choice. We can ship your designs straight from the investment, totally finished and ready for use, or from any intermediate stage. We have vibratory finishers, tumblers the size of a small automobile and a fully equipped and staffed finishing and polishing room at your disposal. Of course, a finished piece is more expensive than a raw casting and hand finishing is more costly than machine finishing.

A Brief History of Lost Wax Casting

   Our shop produces investment, or lost wax castings a casting technique dating to antiquity.  It was rediscovered in 1897 by B.F. Philbrook of Iowa, who used it to cast dental inlays.  Industry paid little attention to this sophisticated process until the unguent military demands of World War I overtaxed the machine tool industry.  Shortcuts were then needed to provide finished tools and precision parts, avoiding time-consuming machining, welding and assembly.

    Estimates project that castings are used in 90% or more of all manufactured goods and in all capital goods machinery used in manufacturing.   The diversity in the end use of metal castings is a direct result of the many functional advantages and economic benefits that castings offer compared to other metal forming methods.  The beneficial characteristics of a cast component are directly attributable to the inherent versatility of the casting process.  In terms of component design, the lost wax casting process offers the greatest amount of flexibility of any metal forming process.  The lost wax casting process in ideal because it permits the formation of streamlined, intricate, integral parts of "near net shape" obtainable by no other method of fabrication.  The shape and size of the part are primary considerations in it's design, and in this category, the possibilities of lost wax metal castings are unsurpassed.  The flexibility of lost wax cast metal design gives the engineer wide scope in converting their ideas or an existing machined part into an engineered cast part. 

    The freedom of design offered through the lost wax metal casting process allows the designer to accomplish several tasks simultaneously.   These include the following:

  • Design both internal and external contours independently to almost any requirement.

  • Place metal in the exact locations where it is needed for rigidity, wear, electrical conductivity or other engineering consideration

  • Produce a complex part as a single, dependable unit.

  • Minimize surface finish issues by utilizing the fine "as cast" surface of a lost wax casting.

    Our lost wax casting process involves pouring molten metal into a cavity that is close to the final dimensions of the finished component therefore, it is the most direct and simplest metal forming method available.  Our lost wax casting process allows almost any shape or degree of complexity and allows the use of difficult design techniques such as undercut and curved or reflex contours that are not possible with other high production manufacturing processes. 

    Because shape is not restricted to the assembly of preformed pieces, as in welding processes, or governed by the limitations of forging or stamping, our casting process encourages the development of attractive, more readily marketable designs.   The smooth, graduated contours and streamlining that are essential to good design appearance usually coincide with the conditions for easiest molten metal flow during casting.  They also prevent stress concentrations upon solidification and minimized residual stresses in the final casting.  Because of the ability of our mold material to duplicate fine surface detail virtually any surface finish or treatment is possible.  

    The inherent design freedom of lost wax metal casting allows the designer to combine what would otherwise be several fabricated parts needing assembling or, a multiple step machined part into a single step intricate casting.  This is significant when exact alignment must be held for multiple parts in final assembly of stamped or machined parts.  1.
