Common Issues of Z95 Series Hot Box Core Shooters
1.Equipment Adaptability and Model Selection
Q: What is the weight range of sand cores that the Z95 Series core shooters can produce?
A: This series covers the production of sand cores weighing 20–35 kg. The Z956K is suitable for small, complex sand cores under 20 kg; the Z957K for 20–25 kg sand cores; the Z958K for 25–30 kg sand cores; and the Z959K for medium-to-large sand cores of 30–35 kg. You can select the exact model based on the specifications of your casting sand cores.
Q: What types of casting sand cores are suitable for production with the Z95 Series core shooters?
A: The series is specially designed for medium-sized sand cores with complex cavities, such as water jacket cores for automotive engine blocks, complex inner cavity cores for hydraulic valve bodies, and sand cores for construction machinery parts. It is particularly suited for production scenarios where sand cores have large inner cavities and the recovery of uncured coated sand is required.
2.Cost and Consumables
Q: What is the recovery rate of coated sand for the Z95 Series?
A: Featuring a dual-design of tilting sand discharge + vibrating sand discharge, the series achieves a 60%–70% recovery rate of uncured coated sand. Compared with traditional hot box core shooters, it can reduce the procurement cost of coated sand by approximately 30% per production batch.
Q: Besides coated sand, what other consumables are required for the operation of the equipment?
A: The main consumable is coated sand. In addition, wearing parts such as sand shooting nozzles and sealing rings need to be replaced regularly.
3.Technology and Operation
Q: Does the PLC control system of the Z95 Series support customized programming?
A: Yes, it does. The PLC program can be custom-written according to customer requirements, including production cycle, sand core curing temperature/time, and sand discharge parameters. It is fully adaptable to the production process requirements of different casting sand cores.
Q: Is professional training required to operate the equipment?
A: Yes. Although the equipment adopts PLC intelligent control with standardized operation procedures, operators still need to master skills such as mold installation, parameter debugging, and troubleshooting. We provide free on-site operation training for customers to ensure that workers can get started quickly.
4.Maintenance and Troubleshooting
Q: What are the key points of daily maintenance for the Z95 Series core shooters?
A:
① Regularly clean the sand shooting cylinder and nozzles to prevent clogging of coated sand.
② Inspect the pressure and tightness of the hydraulic/pneumatic systems, and replace aging sealing rings in a timely manner.
③ Clean dust from the PLC control cabinet to ensure proper heat dissipation of electrical components.
④ Lubricate the moving parts of the equipment to reduce mechanical wear.
Q: How to resolve the issue of insufficiently compacted sand cores?
A: Troubleshoot from three main aspects: ① Check if the working pressure is within the standard range of 0.3–0.6 MPa; adjust the pneumatic/hydraulic system if the pressure is insufficient. ② Check for clogging of sand shooting nozzles; clean them promptly and replace worn nozzles. ③ Verify the quality and temperature of the coated sand; use coated sand that meets process requirements and control the sand temperature within a reasonable range.
