Ensuring Surfaces are free of any roughness. Some customer processes require a smooth surface to avoid particle generating surfaces during deposition.

Our thermographically controlled lathes are high technology production machines that allow us to produce a wide range of glass and quartz products by hot forming operations. From tubes or rods, these machines can shape by using any combination of forming, pushing, pulling, blowing, sealing, collapsing or centrifugal operations, providing a very high dimensional accuracy.

LTD Material maintains the range of equipment necessary to fully process material in house without relying on outside processing. That combined with our reserve capacity allows us to respond quickly to customer’s needs for custom quartz or ceramic products. We utilize state-of-the-art equipment and methods that allow us to achieve the industry’s highest standards and very precise tolerance levels. Our team of machinists and engineers have many years of experience allowing them to tackle any challenge.

LTD Material offers various types of cleaning for your specific need. LTD is delivering parts used in the most sensitive deposition processes in the fab. These processes require very clean surfaces to avoid particles due to delamination from the quartz surface.

Welding two pieces of glass together is very similar to the process used to join two pieces of metal via oxyacetylene or TIG welding. A rod of the material being joined (in our case, pure fused quartz) is fed into a liquid weld pool, which in turn is generated by a hand held torch.

Our CNC laser cutting capability ensures highly accurate cut out features. This allows for accurate location of inlets and outlets on our complex process tubes. Our expertise allows for repeatable profiles of gas dispersion holes both on round injectors and flat showerheads.

The ability to convert feedstock into the tube sizes required for product gives us flexibility to react to customers’ needs. Out of 3-5 different feedstock sizes we can produce any tube size up to 640 mm. But let us know your needs as we are always pushing the limits.

At LTD Material we strive to be the premier leader in providing an extensive range of products from simple discs to complex components used by the leading semiconductor manufacturers and quartz fabrication companies in North America, Europe and Asia.
