Do Not Blame The Powder
What is the main problem with my oven’s efficiency ?
The main problem is the curing of the paint or powder. The ovens cannot cure the paint in the time allocated by the speed and production demand requirements.
What would Heraeus suggest?
Because of the size of the parts and shape the only solution is a booster section to the original ovens.
What is a booster section and how will this help me as a customer?
A booster section is installed next to or in the original oven. It will raise the temperature of the parts very quickly, say to 100 o/c. The paint, powder can be applied or heated in the booster section. The main oven can then quickly cure the parts for production in less time. On average a booster section can be 20 to 30% quicker in production time and efficiency. You can have both IR electric or Gas.
Have many Heraeus customers looked at this before?
Yes; We have supplied numerous Gel systems around the world and these prove to be particularly popular as they Pre Gel the powder, paint before entering the convection zone. This significantly reduces the likelihood of powder, paint being removed from the surface of your parts which can cause contamination within the oven.
In addition the faster ramp rate on the product during this pre-gel stage can allow line speeds to be increased by 20-30% and will often result in a better finish on the final product.
We also have a fully equipped finishing line here at our test centre where we can simulate an IR pre-gel followed by convection curing to demonstrate the effectiveness of our technology
What is the costs and why should we spend money in a difficult time?
The costs are a fraction of a new oven, can be installed and built by Heraeus which will last many years. Clean and very little maintenance required. Also the speed of your line increases so a big increase in production time. The pay back is often very quick.
I look forward to your reply.
