Request Information


Offshore Technologies represents a U.S. company that specializes in providing a wide range of castings and forgings sourced throughout the world including China, India, S. Korea, South Africa, and Vietnam. Instead of simply being an overseas sourcing company, this represented company provides a total solution for your international sourcing requirements. We deliver quality driven, competitively priced components by focusing on the following:
  • Strategic business relationships with world-class suppliers of castings, forgings, and machined parts
  • Continual quality assessment and audits of these overseas suppliers
  • State-of-the-art supply chain management
  • World-class engineering, quality, and customer service
Engineered components are sourced from ISO and/or TS certified suppliers. Overseas offices are staffed by U.S. trained company employees and include project management personnel, quality personnel, and engineering managers.

The Offshore Technologies personnel have extensive knowledge of the various casting and forging processes. If your company needs assistance in determining which casting or forging process best fits your design, we will be glad to help. Our years of experience in the foundry and forging industries, providing our customers with options that best fit their requirements, is one of the key reasons companies turn to Offshore Technologies.

Additional services and capabilities include:
  • Review of submitted drawings/CAD models for casting, forging, and machining processes
  • Provide assistance in the choice of materials and proper casting/molding/forging process
  • Prototype development
  • Quick turnaround on quotes
  • Provide assistance on conversions from fabrications to castings or forged parts

Sand Casting Specifications (Reference Only)
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Good part price; flexible design; lower tooling costs Less precision than other processes; rougher surface finish All 1 oz to Several Tons 200-250 RMS Yes All Metals ±.020 up to 10" then add ±.001/in thereafter .5° - 3° Low to Medium Cost




Investment Casting Specifications (Reference Only)
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Excellent surface finish; near net shape/net shape capability; complex coring possible Multi-step operations increase costs; need for a pattern for each part which adds to costs <2000 <25 lbs but larger sized parts are possible 63-125 RMS No All metals ±.005" up to 1" then add ±.005/in thereafter No Draft Required High Cost




Die Casting Specifications (Reference Only)
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Close tolerance, complex shaped parts; cost effective for higher quantities; good repeatability; good surface finish Generally ideal for castings less than 25 lbs; high tooling costs; issues of porosity >2000 pcs <40 lbs 63 RMS Yes Aluminum, Mag, Zinc, ZA ±.002"/in 1° - 3° High Cost




Permanent Mold Specifications (Reference Only)
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Good surface finish; close dimensional tolerances; uniform mechanical properties Tooling more expensive than sand casting process; higher quantities normally desired >1000 pcs <100 lbs 100-250 RMS Yes Aluminum, Zinc, ZA ±.015" to 1" then add ±.002/in thereafter 2° - 4° Medium Cost




V-Process Specifications (Reference Only)
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Good dimensional accuracy' excellent surface finish; limited gas holes Special pattern equipment required; generally a low to medium volume process >All <150 lbs 125-150 RMS Yes Aluminum ±.020" to 6" then add ±.002/in thereafter No Draft Required Medium Cost




Plaster Mold Specifications (Reference Only)
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Good surface finish; complex shaped parts; close dimensional accuracy; prototype for die castings Not competitive with sand castings or permanent mold on higher volumes because of unit costs; limited to non-ferrous materials <2000 pcs <100 lbs 63-125 RMS No Aluminum, Zinc, ZA ±.010 to 8" then add ±.001/in thereafter .5° - 2° Medium Cost




Metal Injection Molding Specifications
Benefits Limitations Typical Quantities Typical Part Size Surface Finish Draft Required Metal Options Typical Tolerances Minimum Draft Required Typical Tooling Cost
Close tolerance, complex shaped parts; high quantity process; excellent surface finish; good repeatability; properties similar to wrought material Smaller parts are desired due to powder costs; generally need larger quantities to compensate for higher tooling costs >5000 pcs <1 lb 32 RMS No All Ferrous Metals ±.003/in No Draft Required High Cost
