Powder Coating

PowderTech Corporation offers diecasters, extruders, and fabricators an extensive historical knowledge base and specialized processes to produce defect free powder coated products with high quality outcomes.  We are also ISO-9001:2008 certified.  Quality is our number one priority.

PowderTech's two 6 stage automated systems include:

1.  State of the art Zirconium based conversion pre-treatments. The same treatments auto manufacturing OEM's now use.

2.  Specialty off-line pre treatment processing to mitigate outgassing issues

3.  A wide choice of colors, textures, and resin systems (Epoxy, Polyester, Urethane, Hybrid, TGIC, Nylon).  PowderTech uses corporate approved vendors and certifies to corporate specifications.

4.  Unsurpassed application quality using state of the art Nordson equipment and  climate controlled environmental rooms.

5.  Computerized part records, part histories, part photos, and files outlining part specific work instructions, and SPC controls

6.  A Quality Management System with ISO-9000 / AS-9100 level support.

7.  Specialty coatings / Anti-graffiti, EFI coatings, non-skid coatings, other specialty finishes.

8.  A complete laboratory with testing capabilities for Salt Spray, Impact, Taber Abrasion, Adhesion, Coating Thickness, and Color Accuracy Analysis.

While the powder coating process has been in commercial use since the late 1960’s, the continued emphasis on long term paint durability and green processes has moved powder coating to the forefront of the paint finishing market.

Along with durability, the technological change in thermally cured paints continues to benefit from broad advances in metal pre-treatment technology and polymer science.  Resistance to corrosion, abrasion, and UV issues continue to make quantum improves with each sucessive year.  Esthetically, powder now has many more options when it comes to specialty paint.  Wrinkles, hammertones, metallics, veins, and antiques are now used to produce unique looks as well as functional excellence.

Castings (sand, gravity, low pressure or high pressure) provide  a valuable and cost effective method of manufacturing strong lightweight parts with complex geometries.  They continue to grow in use and are a staple in a multitude of manufactured products.  Powder coating remains the best method of providing esthetic quality and a durable protective film on cast parts and products.

Powder coating die castings however can lead to special challenges in producing a quality final product. Powder coating, because of its thermal cross linking component, requires temperatures of 350 to 415 F for the paint resins to activate.  If castings are not pre-processed correctly, many rejects are often the net effect.  Some of the problems that commonly arise when powder coating castings include but are not limited to:

·          Surface Blistering

·        Porosity

·          Out-Gassing

·          Pin-Holing

·          Surface Scale & Oxidation / Adhesion Loss

·          Cold Shut Marks

PowderTech incorporates numerous specialty pre-processes that virtually eliminate surface defects in the final painted product.
