As to plastic products molding, stable and optimized production process is very important to improve the product quality and production efficiency. HADRDEGA DF series hot air dryer is the best solution to get rid of the surface layer moisture from plastic raw material whose moisture absorption is weak. And it can also apply to the preheating of the raw materials, to make important process parameters to be controlled, to improve the product percent of pass, and to effectively improve the service life of molding host screw.
Hot air dryer
DF series hot air dryer has two installation forms for customers to choose, the models under DF5000 can be chosen of side hanging type, installed directly on the side wall of dry insulation material barrel, models above DF6000 are all floor type, can be installed on the bracket of dry insulation material barrel, with drying capacity range varies from 5 to 3000 kg/h.

Raw material preheating can increase the processing efficiency of the machine, also can reduce energy consumption. Using hot air dryer to preheat the raw material can save 38~40% of energy consumption than heating the raw material with the make-up machine, because with double insulation dry material barrels, and with a return air heat exchanger, can save 50~60% of energy consumption compared to ordinary dry machine.
Quality
Customers need high performance equipment to continuously ensure that they have the high quality products, HADRDEGA hot air dryer is to meet the expectations of high quality and the always insistence of the device performance under fierce price competition, HADRDEGA hot air dryer and other HADRDEGA products, are manufactured strictly according to CE standard.
Product advantage

By return air exchange system, 55-60% of the energy consumption can be saved
Simply operation
With intelligent temperature control system, self temperature setting, real-time drying temperature display and fault alarm indicator, etc
Chrome Plating Production Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Chrome plating refers to the act of plating chromium as a plating layer on other metals.
Chromium is a kind of silver-white metal with a bluish tint. Metal chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of precious metals.
The chromium-plated layer has a very high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. The friction coefficient of the chrome layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance.
