Originated in the 1970s, the cold box process has evolved over half a century into the mainstream core-making technology of the casting industry. With the continuous expansion of the casting market and tightening environmental regulations, foundries are confronted with multiple pressures concerning output, quality and environmental compliance. Xinda keeps optimizing its cold box resin system and builds a complete cold box resin product portfolio to deliver customized optimal core-making solutions for foundries across diverse application scenarios.

I. Green R&D Breakthrough: Balancing Low Emissions and Superior Performance

Stringent environmental requirements represent a key challenge facing the casting sector. For years, Xinda has focused on green technology development for cold box resins. By optimizing resin formulation, we reduce organic content in the system and effectively cut hazardous gas emissions during core making and pouring, improving workshop working conditions and helping customers meet environmental compliance standards.

Environmental upgrading does not come at the expense of core performance. Key properties including core strength and release performance are well maintained or even enhanced under certain working conditions. We solve the common industry pain point that eco-improvement usually sacrifices usability, achieving a perfect balance between low emissions and outstanding performance.

II. Core Advantages of Cold Box Process for Stable and Efficient Casting

Supported by Xinda cold box resin system, the technical strengths of the cold box process are fully unlocked to meet mass production demands for high-quality castings:

1. Flexible mould selection with lower investment

   No heating of core boxes is required. Moulds made of plastic, wood or metal are all applicable, cutting mould investment and production line modification costs.

2. Proven stable process & high productivity

   The core-making process is fully verified on site with reliable stability and fast cycle time, suitable for continuous large-scale production.

3. High capability for premium castings

   Enables the manufacture of high-quality castings with intricate structures and high dimensional accuracy, catering to high-end casting demands from automotive, engineering machinery and other sectors.

4. Excellent comprehensive sand core properties

   Sand cores feature outstanding shakeout performance for easy casting cleaning, long storage life for flexible production scheduling, and low resin addition rate to reduce raw material consumption.

5. Good reclamation performance of used sand

   Superior reclamation property of used sand minimizes solid waste generation and lowers overall production cost, aligning with green manufacturing.

III. Continuous Innovation in Binder Materials for Casting

Xinda's full range of cold box resin solutions covers various casting working conditions and provides targeted product selection support based on customer specifications. Going forward, Xinda will continue upgrading cold box resin technologies focusing on low carbon, low odor and high performance. We keep supplying stable, compliant and cost-effective core-making materials for foundries and drive the industry toward green, efficient and sustainable high-quality development.
