Acquired by WS Hampshire in 2017, Timco has provided decades of material expertise and been a proven leader in the expanded use of engineered thermoplastics for industrial equipment by improving efficiency and reducing maintenance requirements. WS Hampshire is proud to carry on Timco’s excellent reputation of supplying into production equipment, heavy lifting equipment, and rolling mills while being the largest supplier of machined non-metallic sheaves in North America.
Engineering plastics are modern, flexible materials, that are wear resistant and have low coefficients of friction. For decades, engineers have seen metals easily be replaced by plastics. The reasons for switching to plastics vary from application to application, but are most often due to reduced weight, noise, friction, and maintenance requirements. Also, plastics often provide much longer part life leading to significant cost savings for equipment manufacturers and users. A significant reduction in weight increases lifting capacity and may offer a reduction in required drive power. Additionally, the handling and assembly of large parts is made easier. Plastic materials cause very little wear on the contacted surface. For example, wire rope will last two to three times longer when plastic sheaves are used instead of steel. Scheduled maintenance for lubrication of parts is often reduced or eliminated completely when components are manufactured from plastics.
Key Characteristics of Thermoplastic Components
- Low weight – Easier handling, reduction in drive power required, improved lifting capacity
- Excellent price/performance ratio – Extended part life due to very high wear resistance
- Many are self-lubricating – Maintenance requirements can be reduced or eliminated
- Reduction of equipment noise and vibration
- Mating parts are not worn or damaged
- High mechanical strength, hardness and stiffness
- Impact strength even at low temperatures
- High mechanical dampening capacity
- Excellent fatigue resistance
- Good sliding and emergency running properties
- Outstanding abrasion resistance
- Dimensional stability and weather resistance
- Broad chemical resistance
- Will not corrode
Advantages for Using Thermoplastic Materials
- Ideal for Prototyping — After the prototype has been tested, thermoplastics can be melted and re-molded for another production run.
- Reusability — Thermoplastic materials can be recovered and re-melted for future use.
- Higher-yield material — Due to their recoverability, you will see a high piece yield from your overall stock of material.
- Chemical-resistance- Due to its higher level of chemical resistance, this plastic is ideal for medical materials and devices and also other areas where chemical exposure can occur, and protection is needed.
- Recyclability — Due to their ease of melting, thermoplastic materials are suitable for recycling.
