Plastic assemblies in Electric Vehicle Charging Stations

There are many different components that are assembled into plastic parts in an EV Charging unit.

Polyamides and Polyesters offer a wide range of possibilities for applications in the area of battery charging with medium to low mechanical and chemical requirements. Given the ever-higher charging voltages and currents and structural components, the usage of fiber-reinforced plastics and polycarbonate material is increasing, and so the need for high performance screws.

REMFORM® II HS™ screws provide a resistant joint, safe and optimized assembly on a wide range of plastics, from unreinforced to engineered plastics, with great opportunities for cost reductions.

Achieve up to 40% of cost savings

  • No need of previous tapping operations
  • Avoid costs related to cross-threading (scrap, line downtime…)
  • Eliminate cost of the elements to prevent loosening

How to prevent cross-threading problems in your EV Chargers?

When assembling in pre-tapped holes with standard machine screws there’s a potentially high risk of blockage or cross-threading problems. MAThread® screws prevent cross-threading problems and provide great cost saving opportunities.

 

Advantages of MAThread® and MATpoint® screws

• Reduces screw insertion time

• Eliminates the risk of cross-threading

• Eliminates the cost derived from downtime, rework and scrap

How to protect your EV Charging unit from external influences

EV Charging stations are increasingly found in the street or in shopping outlets. Protecting them from vandal attack or unauthorized access is a must to prevent damage or public safety issues.

Screws with TORX PLUS® Tamper-Resistant drive system provides restricted access to interior components keeping all the assembly benefits of TORX PLUS® drive system.

Advantages of TORX PLUS® Tamper-Resistant drive system

• Ultimate torsional strength and geometry configuration allows optimum torque transfer

• Extended tool life allows increased productivity on the assembly line

• Limited access to driver bits ensures integrity of the system
