Hardware products are essential parts in the automation industry, small metal parts in these industries not only plays a very important role in connecting, load-bearing function, but also with very highlight decorative role. In the terminal business, in General, the terminal blocks are usually made up of plastic and metal parts and hardware selection of eight factors are as follows:

1, the tensile strength, yield strength and modulus of elasticity ... Such machines in nature;

2, ductility and flexural fatigue;

3, thermal conductivity and heat resistance (thermal expansion);

4, conductivity characteristics;

5, oxidation resistance and corrosion resistance;

6, precision machining, in particular lead (Lead Frame);

7, the surface flatness and electroplating;

8, weldability (Chip Bonding and Wire Bonding)

Elinker Terminal hardware show:

Compared with the plastic, the materials for the Terminal depends on your selection in the course of the performance of below Elinker electric to explain some common Terminal materials and their characteristics:

1, thermosetting plastics EP
With good geometric stability, water, relative to the tracking index. Flame retardant, at high temperature, excellent stability of thermoplastics, but toughness;

2, glass fibre reinforced polyamide PA-F
Nylon glass fibre has a lot of rigidity and hardness at higher temperatures compared to using non-reinforced nylon. It also applies to overvoltage protection fields. Reinforced nylon absorbs less water than non-reinforced nylon. In addition to the above difference, similarly to other properties of the two materials. Accord with UL94, flame retardant nylon fiber reinforced grade HB to V0 V0 black material in most of these cases;

3, thermoplastic polycarbonate PC
Such as high hardness, toughness and transparency, dimensional stability, good insulation properties and good thermal stability.
Especially suitable for transparent Polycarbonate cover or identifying material. Inorganic acid stability of polycarbonate, saturated fat, carbohydrate, gasoline, oils and fats to erosion. Polycarbonate solvent benzene = lye, acetone and ammonia tolerance of difference. Stress cracks can form when certain chemicals and exposure;

4, PBT thermoplastic polyester
PBT has a good geometrical stability, using a glass-fiber-reinforced materials with high strength and heat resistance. Also has excellent flame resistance and electrical properties of reliability;

5, a thermoplastic polyamide 6.6
Quality Terminal in combination with high insulating enclosure requirements, most made from thermoplastic polyamide 6.6, the plastic can be economically by injection molding processing, environmental protection and recycling.
