Qingdao Nanchen Simple Steel Shot Shell Molding Line
The Simple Steel Shot Shell Molding Line is a lightweight, low-cost shell molding production line. It uses resin-coated sand to produce high-strength thin-shell molds, employs steel shots as the filling and supporting medium to replace traditional molding sand, and incorporates simplified conveying, shakeout, and reclamation systems to achieve batch production of castings. The "simple" version typically adopts an open indexing layout and semi-automatic control, retaining the precision advantages of shell molding while significantly lowering investment thresholds and operational complexity.
Equipment Composition of the Simple Steel Shot Shell Molding Line
The Simple Steel Shot Shell Molding Line generally consists of four core units, with automation structures simplified compared to fully automatic circular lines.
1.Indexing Pouring and Cooling Conveying Unit:
Open rail + flask carriages, shot filling machine, and vibrating compaction table. It achieves indexing conveying of flasks, steel shot filling and compaction, as well as cooling and conveying after pouring. The simple version can be equipped with manual flask arranging and auxiliary pouring.
2.Shakeout and Shot-Sand Separation Unit:
Hydraulic flask turnover machine, vibration shakeout machine, and linear vibrating screen / trommel screen. It turns over the flask to empty the contents, preliminarily separates castings, and then separates waste sand, broken shell sand, and steel shots through screening.
3.Steel Shot Cooling and Storage Unit:
Cooling drum, bucket elevator, and shot storage bin. It cools the screened high-temperature steel shots down to the process-required temperature and conveys them back to the shot filling station for recycling, ensuring stable steel shot circulation.
4.Dust Collection and Control System:
Equipped with a pulse-jet dust collection system covering dust-generating stations. The control system adopts basic PLC interlocking to achieve semi-automatic operation of indexing conveying, shot filling, and flask turnover, with manual assistance at key operating stations.
Advantages of the Simple Steel Shot Shell Molding Line、
1.High casting quality – the shell mold offers high precision, resulting in tight dimensional tolerances and significantly reduced subsequent machining allowance. The forced cooling by steel shots promotes a dense casting structure with fewer internal defects, effectively preventing problems such as mold swelling and runout.
2. Low investment and operating costs – the simple open line reduces capital investment by 30%–50% compared to fully automatic circular shell molding lines. Steel shots can be recycled long-term with extremely low consumption rates under normal production. The consumption of resin-coated sand is greatly reduced compared to traditional green sand casting, and consumable as well as operation and maintenance costs are significantly lowered.
3. Environmentally friendly operation – steel shots generate far less dust than traditional molding sand. With the dust collection system in place, the workshop has minimal sand accumulation and low dust concentration. Noise levels are also much lower than those of conventional clay-sand production lines, meeting green casting environmental requirements.
4. Flexible operation and easy maintenance – the entire line requires only 2–3 operators, with low training requirements. The simplified equipment structure means fewer failure points, and lower maintenance difficulty and costs. The open layout can be flexibly adjusted according to workshop space and accommodates rapid changeover for multiple product varieties.
Applicable Scenarios for the Simple Steel Shot Shell Molding Line
Materials: Small to medium-sized castings in gray iron, ductile iron, general cast steel, non-ferrous alloys, etc.
Typical parts: Automotive brake drums, wheel hubs, valve bodies, pump casings, pipe fittings, hardware tools, small construction machinery components, etc.
