FAQ

What is the delivery lead time of the equipment? Can on-site installation and commissioning be provided?

The delivery lead time for standard models is 15–30 days, and for customized equipment it is 30–60 days (adjusted according to customization complexity).On-site installation and commissioning are provided for all equipment. Professional technicians will carry out equipment installation, commissioning and parameter calibration on site, and provide on-site training for operators to ensure the equipment is put into normal operation.

What casting methods are available for brass casting machines? What brass products are they suitable for producing?

Our brass casting machines mainly adopt three casting methods: sand casting, permanent mold casting, and low-pressure casting, to meet different product requirements:

1. Sand casting: Suitable for mass-produced small and medium-sized brass parts (such as valves, pipe fittings, hardware accessories), with low cost and compatibility with complex shapes.

2. Permanent mold casting: Suitable for high-precision, wear-resistant brass parts (such as bearings, gears, precision components), featuring smooth casting surfaces and high dimensional accuracy.

3. Low-pressure casting: Suitable for large-sized, thin-walled brass parts (such as engine components, large pipe fittings), free from porosity and shrinkage defects.They can produce various brass products used in hardware, machinery, sanitary ware, automotive and many other industries.

How to reduce wear and extend service life during daily use of cutting machines?

Four key points should be noted:

1. Regularly inspect the cutting torch, nozzle, laser head (or waterjet nozzle), and replace worn parts in a timely manner to avoid affecting cutting accuracy and efficiency.

2. Keep the equipment clean by removing waste residue and dust from the cutting table to prevent jamming caused by foreign objects.

3. Strictly adjust cutting parameters (speed, power, air pressure) according to the material type and thickness to avoid overloading operation.

4. Regularly inspect the electrical system and cooling system to ensure proper heat dissipation of the equipment.Our company provides regular inspection and maintenance services.
