Fastener Selection

Technical input on:

• fastener quality standards
• conversion to metric standards
• selection of finishes
• strength requirements, including material and heat treat selection

Product Teardowns

Disassembly and analysis of an entire product to evaluate each component and joint design.

• conducted from a manufacturing, service, and end-user point of view
• utilizes DFM/DFA principles
• identifies possible cost savings from fastener consolidation or replacement, improved assembly methods and reduction of scrapped rejects
• includes report and formal presentation at your facility

Infastech® has performed over 30 teardowns in the last 3 years, from computer hard drives to full-sized cars.

Joint Analysis

• evaluation of prototype design
• improve integrity of existing designs
• troubleshoot in-service problems
• engineering software to aid design, including FASTCALC II and JointWorks

Model Shop

Our model shop and technical center are dedicated to stretching the limits of our design and manufacturing capabilities. Our dedicated model shop provides support for major programs where research and product/process development is crucial to bring various concepts to reality. We can quickly produce prototypes and small lot samples for customer testing to ensure these parts meet your exact requirements before production begins.
 Equipment capabilities:

• Heading size range (diameter x length) #2x1.50” to 3/4 x 4.00” to M20 x 100mm
• Roll thread size range #2/M2 up 1-3/8”/M36

Fastener Consolidation Services

Review and analysis of parts list, product design and assembly in order to reduce costs and maximize joint performance

• streamline inventory by eliminating part numbers
• simplify assembly
• improve service level

Testing

Our state-of-the-art testing facility can analyze everything from your fasteners to your entire assembly, including testing for:

• tensile/compression/shear
• torque/tension with angle analysis
• pull-out/push-out
• joint durability
• fastener fatigue
• clamp retention using thermal soak and cyclic tests
• hydrogen-assisted failure from stress corrosion and hydrogen embrittlement
• fastener drive system, including engagement, wear, fatigue, and ultimate strength
• joint pressure distribution and leak prevention
• molding and optimization of plastic boss designs

Fastener sizes M0.8 to M25 can be tested. Portable equipment is available for use on your assembly line.

Fastener Training Seminars

Technical training on a number of fastening issues, presented at your facility. Subjects include:

• bolted joint behavior
• torque/tension relationship
• tightening strategy
• seating torque development
• fatigue considerations
• plating and finishing
• manufacturing processes
• fastening into plastics
• fastening into metals
• metric standards
• stress corrosion and hydrogen embrittlement
• custom presentations to meet your specific needs

On-site Assembly Evaluations

Organized review of an assembly line and proposal of ideas to reduce overall costs, and:

• improve product quality
• streamline assembly methods
• reduce labor usage
• minimize component costs
• reduce scrap rates
