How Do Manufacturers Know a Material Will Perform as Expected?

Material testing helps verify strength, hardness, toughness, corrosion resistance, fatigue life, chemical composition, and other properties before a material is used in production. Common methods include tensile, hardness, impact, fatigue, corrosion, metallography, and non-destructive testing.

Our latest guide explains 27 common types of material testing, how they work, and where they are typically used.

How much stress can a metal part withstand before permanent deformation begins?

Yield strength is an important factor in material selection and load-bearing component design. It helps engineers determine whether a part can maintain its original shape under working loads.

Our latest guide explains:

• What yield strength means
• How yield strength is measured
• How to read a stress-strain curve
• Yield strength vs. tensile strength
• Typical values for common engineering metals
• Why higher yield strength is not always the best choice

Yield strength defines the stress level at which a metal begins to deform permanently — and plays a direct role in ensuring safety, performance, and structural integrity in nearly every engineered product.

Reliable electrical components start with a secure contact connection.

In this process, silver contacts are welded onto copper parts one by one. Accurate placement and controlled welding help create a firm bond while maintaining the shape and function of each component.

These welded contact parts may be used in relays, switches, circuit breakers, contactors, and other electrical control devices. 👏

HLC provides custom silver contact components, metal stamping, welding, and secondary processing based on customer drawings.

Spline shafts are widely used in mechanical systems that require reliable torque transmission, accurate alignment, and, in some designs, controlled axial movement.

Our latest guide covers:

• What a spline shaft is and how it works
• Common spline types and tooth profiles
• Key advantages over keyed shafts
• Typical applications in automotive systems, industrial machinery, robotics, and power transmission equipment
• Important manufacturing and selection considerations

Selecting the correct spline profile, fit, material, and tolerance can help reduce wear, improve alignment, and ensure reliable performance throughout the service life of the component.

Precision stamping is only part of the process.

After forming, these copper components undergo secondary machining with dedicated fixtures for stable positioning. Continuous coolant helps control heat, remove chips, and maintain consistent hole quality during batch production.

This process is suitable for copper terminals, contact components, and other precision stamped parts requiring additional machining.
