HTCI, Co. offers the following services related to our casting products:


To assist our customers in a quick turn-around time, HTCI offers machining capabilities using our complete in-house machining facility.

Castings can be purchased machined and ready for plating, assembly, or anything else that is required.

In addition to machined castings, HTCI can supply you with prototypes machined from stock material such as 7075, 6061, etc.

We have a vast array of equipment including three 3-axis CNC vertical machining centers, one 4-axis dual palette horizontal machining center, and one 5-axis vertical machining center.

In-House Special Processes

HTCI offers the following special processes in-house:

CAD Capabilities

HTCI can accept data in a variety of digital formats.

Rapid Prototyping

Rapid Prototyping (RP) is the accelerated product development through the use of a 3D CAD file integrated with advanced laser and machine technology. The end product being a physical 3D model. This process is a solution to accelerate your design to market.

Rapid Prototype Castings

There are several different Rapid Prototype Casting methods, each with their own strengths for different applications. HTCI offers Engineering support to assist in the decision of which method is best for your purpose.

HTCI prefers using prototype patterns made from QuickcastTM materials. This allows for a quick turnaround using our investment casting process.

Rapid Prototype Machining

In lieu of cast prototypes, prototypes from bar or plate stock can be machined in our CNC Machine Shop.

RP Advantages

Designers and Engineers benefit in the following ways by using Rapid Prototype Castings.

Stereolithography (SLA)

SLA is the most popular of the RP Methods. The advantages of SLA are numerous. They include excellent model accuracy, large build envelope, and smooth surface finishes. The hollow QuickcastTM style produces a clean burnout when using the investment casting process.

How It Works

Using STL 3D CAD data, a laser solidifies a liquid resin, one cross sectional layer at a time. Both, solid (ACES) or QuickCastTM models can be built. We require SLA (QuickCastTM) patterns for plaster mold/investment castings.

Selective Laser Sintering (SLS)

SLS enables the user to select different materials that fit their objective while still providing good accuracy of the product.

How It Works

Using 3D CAD data, a laser fuses powdered material creating a model of the part.

Bridge Tooling

Bridge tooling is used for short production castings. RP models are duplicated into epoxy tooling.

How It Works

Using a RP model as the master, eposy is poured around it to produce wax patterns or dies.
