At Unitech Machinery Ltd, we design, manufacture and install specialist equipment such as powder coating ovens/curing ovens to support paint finishing and surface coating industries, both at home and overseas. We are a Midlands based manufacturer and our range of powder coating ovens and curing equipment is huge; comprising of conventional box and tunnel ovens with multi fuel options and a temperature range from 40°C to 550°C.
What is Powder Coating?
Powder coating is a dry finishing, multi-step process. The three main steps are:
1. Cleaning and preparing a product prior to powder coating.
2. Coating and spraying the product with a fine powder.
3. Heating and curing the product in a special oven (most often known as curing ovens).
At Unitech Machinery, we can provide all the necessary equipment to take these steps and as a result, achieve a quality and professional finish.
Pre-treatment – Before coating the product with powder, it’s important to ensure the product is clean and free from any contaminants. Any pre-existing paint, rust or other abrasive materials need to be removed in order to complete the surface preparation. This process is completed using compressed air and is carried out in a safe, efficient enclosure for abrasive blasting. A water wash spray booth can be used if the product is covered in any residue. Hot water or steam is used to clean and rinse the product to improve finish quality. As a further precaution, our dry ovens can be used to heat up and evaporate any remaining water from the recently washed product.
Application – Depending on the type of product being coated and to get a quality finish, you’ll need a spray booth which is configured to your needs. Our spray booths provide well lit areas for the application of powder coating and are manufactured with exhaust fans to contain and filter overspray. The whole process is completed using a professional powder coating gun which offers reliable results.
Curing – Once the product is powder coated, it’s moved inside a powder coating oven where the temperatures can range from 40°C to 550°C. The product is then heated up to a certain temperature with it stabilising for a set period of time. When the curing process has finished, the product is removed and allowed to cool before handling.
Our industrial curing ovens are designed to improve the strength and durability of a material by accelerating and causing a chemical reaction. It’s able to achieve this by raising the temperature of a product to a specific limit. For example, when used in powder coating, the powdered molecules heat to a point where they bond with each other and are able to fully coat the surface.
The products and processes we offer range from heat treatment to paint curing of all metal and plastic substrates. We develop ovens for any size, whether its test pieces or heavy-duty construction equipment. Unitech Machinery can help. All ovens (including our powder coating ovens) are bespoke. This ensures that the design and manufacture completed in-house, meets the client’s precise requirements. The equipment that we supply can fully integrate with our client’s other plant and equipment. Our ovens provide long and trouble-free service at a realistic competitive price.
