STi Custom Manufacturing - Lehigh Valley, PA



  • Product Management

    Here’s where you’ll start – meeting and discussing your project with our Project Manager – responsible for the oversight and status of all projects, and primary support for project-level activity to ensure that your overall goals will be met. Our Program Managers perform activities related to schedule, resource management, and cross-functional execution, capable of doing “whatever it takes” to make your product a success and your relationship with us beneficial to both parties.

  • Design and Engineering

    Have an idea for a new product that needs to be designed, developed and brought to market?  Start with our talented Mechanical, Electrical, Electronic and Software (Embedded and Application) Product Development Team for complete product design and development – from initial concept to final design.  Our service includes use of a full suite of sophisticated CAD solutions including Finite Element Analysis (for mechanical designs) and Signal Integrity Analysis (for electronic PCB designs).  Upon your approval and request, we will build you complete working prototypes, using 3-D printing (via one of our rapid prototype partners) in combination with our own in-house R&D prototype fabrication and assembly capabilities.

  • Purchasing and Planning

    Once you are satisfied with the final design and approve it for full-scale production, it enters our system under the watchful eye of your Project Manager, who works on scheduling with our Production Coordinator. We use an end-to-end ERP solution that allows us to streamline and support our front office operations (including Purchasing) and our manufacturing process for efficiency and time (and cost) savings. Simply provide us with your projected needs and we will make sure you have what you want — when you want it!

  • Fabrication

    STi has over 22 years of experience in all types of metal fabrication.  We can create simple or complex custom fabricated metal assemblies using all types and sizes of sheet metal parts (via our long-time partner Daria Metal Fabricators), and all types, shapes and sizes of HRS, CRS and aluminum stock (tubing, angle, flat-stock, channel, etc.).  Our capabilities include sawing, punching, forming, bending, plasma cutting, grinding, etc.  We also have an aluminum Profile Machining Center, and multiple welding stations (pulsed MIG for both steel and aluminum).  If your design requires custom precision-machined components, we can source those through one or our partners as well.

  • Prep and Paint

    After fabrication is complete, all metal assemblies are completely de-burred, all welds ground smooth and all sharp edges removed.  Next they are cleaned in a high-temperature, high-pressure Iron Phosphate Pre-Treatment process, followed by the application of a very durable finish — an Epoxy Primer and an Aliphatic Urethane Top-Coat in the custom color of your choice.  If your application calls for hot-dipped galvanizing, we have a partner for that as well!

  • Electronics and Cabling

    Using our fully automatic CNC wire cutting and stripping machine along with a complete line of Molex and Amp presses, we can create anything from simple jumper wires to very complex wire harness assemblies.  All wire harness assemblies are 100% tested via an automatic tester that checks for continuity, resistance and correct pin-out.

  • PCB Board Assembly

    Our 100% Lead-Free SMT line is capable of assembling SMT PCB assemblies from as small as 4”x 4” to as large as 25” x 25” in a 100% static-free and environmentally controlled (for temperature and humidity) Clean Room.  If your PCB assembly is too complex for our line, we can have one of our long-time PCB assembly partners assemble it for you.

    Additional capabilities include hand soldering of connectors and larger through-hole components or devices, programming and testing of assembled PCBs and precision conformal coating using our brand new state-of-the-art Nordson Asymtek CNC Conformal Coating Machine and UV Cure Oven.

  • Product Assembly

    We are equally skilled at both very light and moderately heavy assembly. We can assemble anything from small electronic devices and controllers up to large towable trailers that serve a variety of functions. For heavy and/or large assembly we have two assembly lines with multiple overhead 2-ton cranes with a minimum lift height of 18 feet.

  • Inspection and Testing

    Absolutely nothing leaves our facility without the scrutiny of our Quality Assurance Team. Throughout the entire manufacturing process, each and every component, subassembly and final assembly is inspected, tested and approved per pre-established, pre-approved and fully documented procedures to ensure the quality we promise is delivered.  All inspection records are maintained for 10 years.

    If a failure or deficiency does occur after delivery, we can track down when, where and why the problem occurred and implement changes to eliminate the source of the failure, thus preventing it from happening again. Note: rejected components or subassemblies are not simply discarded or repaired. Per our ISO Corrective Action Procedure, we conduct root cause analysis: tracking down and eliminating the sources of non-conformances to eliminate future problems.

    Our dedication to continuous improvement ensures your products will have extremely low failure rates — leading to high levels of customer satisfaction, low manufacturing costs and very low warranty expenses.

  • Logistics

    Need help getting your products to your facilities, distributors or directly to your customers? We can help with that too!  We have an independent freight company that is headquartered out of our facility to provide customized door to door LTL or full truck-load deliveries, or if you prefer, our experienced logistics staff can arrange for shipping using the carrier of your choice.

    Additionally, our logistics staff has extensive experience shipping products to international destinations as diverse as Canada, Australia, Europe, South America and the Middle East!

  • Customer and Product Support

    Our commitment to you and your product does not end when your product leaves our facility.  If desired, we can supply post-delivery customer support, including training and technical assistance, standard and warranty repair services and parts support.  Just let us know what you need!

  • Let's Get Started!

    To get your ball rolling, call 484-223-2074 and ask for Bob Miller.  We will answer any questions you might have, then arrange a visit so you can see the STi facility for yourself and meet the team that will produce your product. Let’s do it – together!
