Production Introduction
No Bake Resin Sand Molding
During large-small foundry part production,in order to improve productivity and ensure the quality, the combined no-bake sand flexible molding production line is usually applied,which is made up of preparation station,molding station,solidfication station,stripping station, cart,coating station,surface drying station,core assembling station and auto sand cast molding line,etc.
The main characters are:
The table dimension, load capacity of each equipment and production time and process flow in molding line can be decided according to user requiement.
The whole line adopts PLC centralized control,with high automation degree and process staility.
Motorized roller is designed to sectional style with flexible production organization.
The car movement and rotary machine rotation are controlled by AC frequency converter, with stable operation,convenient speed adjustment and correct positioning.
The whole line equipped with complete detect system which can detect correct position of core box or tray and send signal to auto control.
Multi pneumatic positioning devices equipped on the motorized can keep core box and core plate in correct position.
Electrical control system mainly includes PLC, programmer,AC frequency converter, touch screen, shock resistant proximity switch and control cabinet,etc. The line is equipped seceral panels, which can manually operate the whole line. The panels are equipped with E stop and fault indicator.
No Bake Resin Sand Preparation Reclaimation Plant Line
It should be designed appropriately based on the layout of the casting workshop, process nature and requirement of production program. mainly composed of used sand recovery, used sand broken and regeneration, used and magnetic separation, used sand screen, used sand air separation, temperature adjustment, new sand system, new and used sand storage, sand mixing, molding,core making,environmental protection,electrical control system,etc.
No Bake Resin Sand Reclamation complete equipments plant as per its different process can be divided into Furan Resin Sand Reclamation Plant Line, Alkaline phenolic resin sand reclamation plant line and phenolic urethane no-baked(Pep-set) sand reclamation plant line.
Presently, we can offer resin sand plant with capacity 10t/h,15t/h.20t/h.25t/h,30t/h,40t/h,60t/h ,80t/h, 100t/h, and no-standard vibratory table,lifting device, turnover and draw pattern machine,etc. after years of development, we not only optimal design such as reclaimer,mixer, but also break though in the selection of new material. Our company has ability of undertaking turn key project from shakeout,crusher,reclamation,sand cooling,conveying sand molding.
