Manufacturing technology of four-cavity molds

1. PEO ( Plasma Electrolytic Oxidation )

• 1) New Surface Treatment Technology for Magnesium, Aluminum, and Titanium
• 2) Induce disruption (breakdown) of high voltage on base metal (substrate)
• 3) The surface of the metal is strong, with low porosity and modified into the metal oxide ceramic layer with the good adhesion

2. Anodizing

• 1) Thick oxide film formation on aluminum surface by electrochemical method
• 2) Improved corrosion resistance and abrasion resistance
• 3) Aesthetic glass can be dyed in various colors

3. Chromate

• 1) Formation of oxide film by chemical reaction between chemical solution (acid) and aluminum
• 2) Conductive film, excellent corrosion resistance, and excellent adhesion
• 3) Easy to use for complicated shape structures
• 4) Mass production available

1. Powder coating

1) What is powder coating?A coating method using a powdery resin in which conductor is coated with synthetic resin in powder form.
When the coated object is pretreated and powder having a particle size and specific gravity suitable for electrostatic painting is applied, it passes through the drying furnace at a temperature of 180 °C for 20 minutes, the powder gradually melts into a liquid, becomes hardened, and is cured onto the coated object.

• The coating thickness is about 60 microns
• Actual organic solvent or water is a useless ingredient for film formation, therefore, remove such ingredient and use only resins

2) Electrostatic Powder Coating MethodA method of spraying a negatively charged powder under high voltage onto a grounded substrate to electrically adhere it to the coated substrate, followed by heating and dissolving.
Powder coatings, once attached, generally do not fall off from the substrate during setting because they are difficult to be discharged due to their high electrical resistance and when the powder coatings are attached to a certain thickness, they strongly repel each other and do not adhere with a thickness greater than that (electrostatic equilibrium phenomenon). This phenomenon makes the film thickness of the coating uniform.

2. Corrision Painting

1) What is a corrision painting?A coating method for forming a coating film using a varnish by covering drawings of ingredients for protection of ingredients, aesthetics, etc

• Particularly excellent weatherability, excellent gloss and gloss retention, excellent color and color retention
• Good coatability
• Excellent mechanical properties, chemical resistance, and adhesion
• The stoving temperature is generally higher than 150 °C compared to amino alkyd resins
