We design and built different types of spray plants for plastic and metal parts with water curing oven .we also provide dip pre-treatment plantmonorail with hoist and PLC operated transporter complete with controlpanel .We also provide & tanks pre-treatment plant.
Dipping type cake plate pretreatment production line
This is a conventional pre-treatment where in the plant cost is less and issuitable for low volume production lines. The chemicals are stored inthe MS/SS fabricated tanks. The components are placed in the baskets orcages and they are dipped in each process tank for pre-fixed period oftime. The movement of the basket or cage can be either manual; with amonorail and hoist or automatic with a transporter system.
Immersethe treated workpiece in surface treatment tank filled with liquid,acertain period of time of chemical reaction and cleaning will finishdegreasing, rust, phosphating, passivation,washing processes and etc.
Technology Process:
Pre- degreasing—degreasing—washing1—washing2—pickling—washing1—
balance—washing2—surface adjusting—passivation—phosphating—washing1
—washing2—washing with pure water—drying
Features:
1. Stable tank liquid component and reliable technology
2. The different surfaces of complex workpiece can be dealt with in good effect.
3. Simple structured, easy manufacturing, low investment cost, quick start, quick gains.
4. Large tank volume, liquid input once, long-time warminga
5. Technology time is quite long.
6. Not suitable for surface treatment of the floating objects.
TankBody System:According to liquid's chemical properties, specifictechnology needs, investment intentions and other factors ,materials ofcold sheet, glass steel, stainless steel, PVC, PP can be used. Accordingto liquid's chemical properties and user's habits,the overflow mouth, pollution point and sewage outfall can be determined.
Heating System: Energy method: electricity, steam, natural gas, diesel, etc.
Material: Q235, stainless steel, PTFE
Heat Preservation System Thickness: Determine the thickness of insulation layer according to temperature.
Material: rock wool, aluminum silicate cotton.
Ventilation System: Determine the ventilation system,acording to liquid's chemical properties, customer requirements.
Material: Q235, glass steel, stainless steel, PVC, PP, etc.
Liquid Agitating System: Mechanical agitation, air agitation, circular agitating at the outside of tank.
Controlling System 7.5KW below,start direct ;7.537KW, using stars Triangle Start; 37KW over the use of softstart.
