Colored Inserts


Uses for Colored Inserts:
- Inserts with similar appearances
- Two same inserts with different measurement systems ( inches & metric)
- Two same inserts with different destinations (inside, outside the product, ...)
- The assembly order process (blues first, then reds,…greens, ...) for you or your final customer
The benefits of colored manual inserts include savings in production, simplifying complex assembly processes, and reducing assembly and maintenance time, all resulting in higher quality and default-free rates. Watch your final customers satisfaction levels increase. The extra measure of insurance you gain is invaluable.

Standard Ultrasonic Brass Insert Details


Inserts International's standard and custom ultrasonic brass inserts are utilized in a wide range of products (electronics, automobiles, tools, ...) and can be installed in a variety of installation types and base materials.
The four main types of insert installation are:
- Manual or Press-in: The insert is pressed into the drilled "boss" or remolded hole, using a standard press.
- Heat-Stake: The insert is pressed into the mounting “boss” hole, using a thermal press, whose heat melts the plastic during the insertion. The plastic then solidifies to lock the insert into the mounting hole.
- Ultrasonic: A high frequency vibration is applied while the insert fastener is pressed into the mounting hole. The vibration creates heat that melts the plastic during the insertion. The plastic then solidifies to lock the insert into the mounting hole.
- Molded-in: The insert is placed on core pins in the mold and the part is formed around it.
The main base standard insert materials are:
- Hard thermoplastics: PA-filled, PC/ABS Blends, PPS, PBT
- Medium thermoplastics: ABS, PA-unfilled, POM (Acetal), PVC
- Soft thermoplastics: PP, PE, HDPE
- Thermosetting plastics: BMC, DMC, Phenolic, Polyurethane, SMC, Tufnol, Ureas
