          Multi-Bard Inserts

          MB Series Inserts

          The advantages:
          Press-in threaded inserts,automation-installation economizes labor
          Agnail and groove design provide high pulling and torque performance
          Designed for thermoplastic plastics（ABS,PP,etc.）
           
          Installation instruction:
          Using mold that matches the inner hole and outer diameter for installation
          The installing bore diameter needs to comply with the size table
          The pressing depth should be parallel to or 0.05mm higher than the plastic surface after installation.

          Q1: What are the main advantages of these press-in threaded inserts?
          A: These inserts offer several key benefits:

          • Suitable for automated installation, significantly reducing labor requirements

          • Unique agnail and groove design ensures high pull-out strength and torque resistance

          • Specifically engineered for thermoplastic materials including ABS, PP, and similar polymers

          Q2: What are the proper installation requirements?
          A: Correct installation requires:

          • Using installation molds that precisely match both the inner hole and outer diameter specifications

          • Ensuring the installation bore diameter strictly complies with the recommended size tables

          • Achieving a pressing depth that results in the insert being flush with or 0.05mm above the plastic surface

          Q3: Why is precise mold matching important during installation?
          A: Properly matched molds ensure:

          • Even distribution of installation forces

          • Prevention of insert damage during pressing

          • Consistent installation depth and performance

          • Maintenance of insert alignment throughout installation

          Q4: What happens if the bore diameter does not meet specifications?
          A: Incorrect bore diameter may cause:

          • Reduced pull-out performance

          • Compromised torque resistance

          • Potential damage to the plastic boss

          • Irregular installation depth

          Q5: Why is the 0.05mm height tolerance specified?
          A: This tolerance ensures:

          • Optimal surface contact with mating components

          • Sufficient material engagement for maximum retention

          • Prevention of sink marks or surface irregularities

          • Consistent aesthetic appearance

          Q6: Can these inserts be used in automated production systems?
          A: Yes, these inserts are specifically designed for:

          • High-speed automated installation

          • Consistent performance in volume production

          • Reduced labor costs through automation compatibility

          • Reliable feeding and placement in assembly systems

          Q7: What materials are these inserts designed for?
          A: These inserts are optimized for use with:

          • ABS (Acrylonitrile Butadiene Styrene)

          • PP (Polypropylene)

          • Other similar thermoplastic materials
