ZZ-400 Dual-station Hot Core Box Core Shooter: Intelligent Manufacturing Revolution of Casting Sand Cores - Industrial-grade Solution with 200% Efficiency Improvement and Scrap Rate <0.5%
In the production of precision castings such as automobile engine cylinder blocks and hydraulic valve bodies, the traditional sand core forming process faces three major industry pain points: low efficiency (single-station capacity <120 molds/hour), large dimensional fluctuations (±0.3mm) and high porosity defect rate (>8%). The ZZ-400 horizontal parting double-shooter double-station hot core box core shooter uses Japan's Omron PLC intelligent control and dual-station collaborative operation technology to achieve a breakthrough upgrade of sand core production speed of 400 molds/hour and dimensional accuracy of ±0.05mm, becoming the preferred equipment in the field of precision casting. This article will deeply analyze the equipment technical parameters, process adaptation solutions and 20+ industry application data to provide enterprises with a full-link guide from production line planning to cost optimization.


1. Core technology advantages: dual-station collaboration and intelligent temperature control system
Dual-shooting head dual-station architecture (meets ISO 8062-3 standard):
Horizontal parting design:
The station spacing is 600mm, supporting Φ400×400mm sand core synchronous injection, and the mold switching time is less than 3 seconds;
The injection pressure is 0.5-0.7MPa adjustable, and the sand core density uniformity deviation is less than 2%.
Collaborative operation logic:
PLC controls the dual-station alternating injection, the beat time is 9 seconds/mold, and the efficiency is increased by 200% compared with the single-station;
Equipped with a vibration sand falling module (amplitude 2-5mm), the sand falling residue is less than 0.1g.
Intelligent temperature control system (accuracy ±1ºC)


Zoned heating technology:
The hot core box is divided into 6 zones with independent temperature control (150-300ºC), the temperature difference is less than 5ºC, to prevent the sand core from warping;
The power density of the electric heating tube is 15W/cm², and the heating rate is 8ºC/min (3 times faster than gas heating).
Key points of strategic selection of ZZ-400
Key points for enterprise selection:
Mold compatibility: Prioritize tooling systems with parting surface positioning accuracy of ±0.01mm;
Intelligence: Equipment with process parameter self-learning function can reduce the debugging cycle by 50%
