In-House & Special Process Services

By maintaining process related capabilities in-house and partnering with industry leaders, Engineered Precision Casting Co., Inc. has ensured the product dependability that is necessary to provide its customers with the cost-effective solution to their design needs.

Rapid Prototype Castings

Engineered Precision Casting Co., Inc. is capable of supplying aerospace grade rapid prototype castings from a CAD file (.STL or other files after translation) with a lead time of only four weeks. With the advantage of directly substituting wax patterns normally produced from injection molding, rapid prototype patterns are a quick and relatively low cost alternative.

  • CastForm Polystyrene (PS)
  • Stereolithography Apparatus (SLA)
  • Selective Laser Sintering (SLS)
  • Thermojet Wax
  • Quickcast Prototyping

Prototype castings are a reliable means to quickly produce tooling grade metal castings while in the preliminary design phases of a project. Rapid prototype castings avoid expensive tooling changes and allow the product engineers the extra time to finalize the design. When considering the competitive edge of prototyping, consider the experience of Engineered Precision Casting.

Injection Tooling & Fixture Fabrication

An investment casting can only be as good as the die that is used to produce it. With this in mind, Engineered Precision Casting Co., Inc. has always designed and produced its own tools and fixtures to ensure complete control of all the critical dimensions of the final part. By employing various software programs, Engineered Precision Casting Co., Inc. is capable of utilizing just about any type of electronic file to fabricate tooling. Additionally, Engineered Precision Casting Co., Inc. accepts transfer tooling with a high rate of success.

Heat Treating & Hardness Testing

By managing its special process operations like heat treating in-house, Engineered Precision Casting Co., Inc. is able to avoid the production delays associated with transit and shared queue times, saving its customer’s time and money. Its gas-quenched vacuum furnaces for heating steel and our drop-bottom aluminum furnaces are surveyed regularly under strict accordance with the AMS-2750 Pyrometry requirements. Part specific instructions, tight process controls, preventive maintenance, qualified personnel, and routine compliance audits ensure that your parts are processed in strict accordance with all contractual requirements. Engineered Precision Casting Co., Inc. is Nadcap accredited for its heat treating and supporting operations such as:

  • Homogenize & Solution
  • Precipitation Hardening
  • Harden & Temper
  • Rockwell Hardness Testing
  • T4, T430, T6, T61
  • Normalize & More

HIPping (Hot Isostatic Pressing)

Hot Isostatic Pressing (HIPping) is the simultaneous application of controlled heat and high pressure to improve the properties and eliminate enclosed sub-surface voids that may be associated with the casting process. Engineered Precision Casting Co., Inc. employs industry leaders to perform this specialized process on highly critical applications.


Welding, Casting Repair

When authorized by contract, Gas Tungsten Arc Welding (GTAW) in accordance with AMS-2694 and customer requirements is utilized to perform weld repair of castings.  Engineered Precision Casting Co, Inc. maintains qualified/certified welders and visual weld inspectors and is Nadcap accredited.

Nondestructive Testing

Engineered Precision Casting Co., Inc. is Nadcap accredited for its Nondestructive Testing operations. Personnel are qualified and certified to various customer requirements and aerospace industry standards such as NAS-410. Training programs, compliance audits, process controls, detailed procedures, and techniques round out a special process program that is dedicated to quality. Nondestructive Testing isn’t new to EPCO…it’s been a part of in-house operations for over thirty years.

  • Liquid Penetrant Inspection
  • Magnetic Particle Inspection
  • Radiographic Inspection

CAD Modeling & CNC Support Machining

Engineered Precision Casting Co., Inc., utilizes various software programs to manage all type of customer supplied electronic files. CAD modeling is utilized for the production of rapid prototype castings and design assistance services. In addition, your project can be quoted from any of the following:

In order of preference, examples of acceptable types of 2D & 3D electronic files include:
