One-Stop Full-Scale Service for Resin-Coated Sand Shell Molding Casting Production Line Filled with Steel Shot
With over 20 years of deep engagement in the foundry machinery industry, Qingdao Nanchen has abandoned the single equipment supply model and developed the Resin-Coated Sand Shell Molding Casting Production Line Filled with Steel Shot (hereinafter referred to as the Shell Line). It is a customizable, multi-scenario integrated precision casting production system that helps global customers achieve the core goals of improving casting quality, reducing production costs and enhancing efficiency.
This Shell Line adopts resin-coated sand to make sand molds and uses iron shots as filling materials to support the molds, focusing on casting precision and sand mold strength. It consists of five modular units: pouring & cooling, shot-sand separation, iron shot cooling & storage, dust removal and control system. Equipped with a PLC linked control system, it supports both automatic and manual operation modes. The production line features compact layout and smooth process connection, suitable for mass production of castings made of various materials. The casting precision error is ≤±0.3%, the scrap rate is reduced by 15%–20% compared with traditional processes, the production efficiency is increased by more than 30%, and the cyclic utilization rate of steel shots reaches 95%, realizing efficient resource utilization.
Sand molds produced by the shell molding process boast high strength, good air permeability and excellent collapsibility. Castings manufactured with this technology feature outstanding geometric and dimensional accuracy, which greatly reduces casting defects and fundamentally improves the internal quality of castings. The standardized process flow is: steel shot filling into shell molds → pouring → cooling → shakeout → part taking → separation and recovery of steel shots and sand. The process is simple, highly controllable, and easy to operate and maintain.
We provide global customers with one-stop full-cycle supporting services from demand communication to commissioning and operation. After order confirmation, our technical team will tailor production solutions and complete customized manufacturing based on customers’ actual conditions, including production scenarios, casting types, workshop layout and site dimensions. High-standard quality inspection is implemented during production; qualified products are delivered worldwide via professional logistics. After equipment arrival, our technicians conduct on-site survey, professional installation and commissioning to ensure compatibility. After acceptance and delivery, we provide commissioning guidance, technical training and a global service hotline, supported by lifetime maintenance, affordable spare parts supply and regular follow-up services.
Customer-oriented to meet production demands, the Steel Shot Filled Shell Line has become the preferred choice for foundry enterprises at home and abroad thanks to its modular integrated design and high resource utilization. It can be flexibly customized according to customers’ workshop layout, production scale and casting types, balancing precision and efficiency. It not only meets mass production requirements, but also fundamentally reduces casting costs and defects. Centered on high-quality products, it truly helps foundry enterprises achieve production upgrading.
