E-coat or Powder Coat?

Having your product coated by a domestic supplier has many benefits.

Anyone who has spent a little time pricing products and services with foreign suppliers versus domestic has no doubt noticed two things: the initial quote for price is much lower overseas, and the most common criticism is that Asian products are cheap and sometimes dangerous. Things from Asia are not always bad or unsafe; if they were, no one would use them. However, the safety record and quality control standards are inconsistent. Good risk management weighs beforehand the cost of being part of someone's mistake.

While manufacturers may find the cheap labor and initial low quotes of foreign suppliers attractive, they need to realize they may lose access to expertise that understands the domestic market, the need for innovation, easy communication, and elevated high shipping costs. In cases where quality becomes an issue, they will be limited in the options available to correct the situation. Manufacturers of metal parts are faced with a choice to either ship the product back (high cost, time delay), or to find another supplier (high cost, time delay). Getting it right the first time is the most cost efficient option and expert product is available close to home

What is the best kind of coating for your parts?

The best coating for parts is situation dependent. Cheap coatings allow rust to bleed through, fading, and shorten the lifetime of the product. Quality coatings for your metal parts can protect for an average guarantee of 1000 hours of salt spray protection.
  • Electrocoating, also known as "e-coat", a positive charge is applied to the paint bath and a negative charge is applied to the parts to be coated. The paint particles are suspended in water. Also, the paint is a special formula that allows an electric current to travel from one paint particle to another until it reaches the part where the paint particles electrically attach themselves to the surfaces of the part. The parts are then processed through a bake oven where the paint is melted onto the part for fusion bonding and then heat cured to form a hard and durable film to coat the part. The cured thickness of the electrocoating film is usually 0.6 to 1 mil.
  • Powder coating is another method for parts painting and has many similar characteristics. However, the "paint" is more of a plastic material in powder form. The consistency is similar to baby powder or face powder. The powder is sprayed through a gun that contains a charging mechanism. The parts are again passed through a curing oven where the powder particles will melt and fusion bond to the metal part then be heat cured to form a hard and durable film to coat the part. The cured thickness of the powder coating film is usually 1 to 3 mils.

So which one is better for metal painting: e-coating or powder coating. If one were "better" the other would never be done. The advantages and disadvantages are application or situation dependent. When you choose a domestic coating manufacturer, you'll increase the ease of communication to discuss your specific situation and what method would work best. You can rely on the safety standards and consistency to receive a safe product. Shipping costs are also dramatically reduced.
