As a purchaser of powder coating services, you deserve the highest quality work done at competitive prices on your time schedule. This is what Smisen is prepared to deliver to all of our customers, from prototype to production runs.
Our in-house powder coating plant ensures tight control on both efficiency and delivery, and guarantees that quality remains our highest priority.
Electrostatic spraying is the most widely used method of applying powder-coating materials. This process is the most efficient and effective means of applying powder coatings.
The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun. The gun imparts a positive electric charge on the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the workpiece by the powerful electrostatic charge.
When a thermoset powder is exposed to an elevated temperature, it begins to melt, flows out and then chemically reacts to form a higher molecular weight polymer in a network-like structure. This cure process requires a certain threshold of temperature for a certain length of time in order to reach full cure and establish the full film properties for which the material was designed. Normally the powders cure at 125°C in 10 minutes.
We have a spectrum of RAL colours, finishes and textures ensuring whatever your requirements, we can deliver the highest quality end product. Powder coating textures range from smooth glossy finishes to matte, textured, or wrinkled finishes. Thick coatings are easily achieved easily through powder coating processes.
Coatings are designed to perform their intended function best when applied within a tight thickness range as specified. This ensures optimum product performance. Powder Coating thickness may also affect the application's impact resistance, flexibility, hardness, edge coverage, chip resistance, weathering, resistance to salt spray, and ability to retain gloss.
To make sure that the thickness of the coating conforms to the mentioned specs, we conduct a Coating Thickness Gauge Test on the powder coated products to accurately & quickly measure the coating thickness of the metals surfaces.
Surface coatings are subjected to mechanical damage by impact which can deform the coating and/or substrate. Applying a variable range of impact load allows for coatings to be tested for elasticity, brittleness and adhesion to the substrate.
The salt spray test is a standardized test method used to check corrosion resistance of coated samples. Coatings provide corrosion resistance to metallic parts made of steel, or brass. Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish.
