● Cooling system
● Control system
● Factory layout
● Auxiliary equipment
The final configuration will be determined after the technical requirements are confirmed.

The chamber size is selected according to the maximum workpiece dimensions, loading quantity, fixture structure, rotation requirements, coating uniformity, and expected production capacity.
A chamber that is too small may limit loading capacity, while an unnecessarily large chamber may increase investment and operating requirements. The chamber should therefore be matched to the actual production plan.

Production capacity depends on several factors:
● Number of products loaded per batch
● Coating cycle time
● Product dimensions and spacing
● Fixture design
● Required coating thickness
● Number of operating shifts
● Pretreatment and post-treatment time
● Equipment maintenance schedule
Huasheng can estimate batch capacity and production output after reviewing your products and production targets.

Yes. Fixture design is an important part of a coating project.
Fixtures may be designed according to the product shape, loading position, rotation method, electrical contact, coating area, masking requirements, and batch quantity.
A suitable fixture helps improve loading efficiency, coating uniformity, and batch consistency.

Integration can be evaluated according to the existing factory layout and production process.
The project may involve product cleaning, pretreatment, loading, coating, unloading, quality inspection, and post-treatment. Huasheng can help plan the connection between the coating system and related production equipment.

The required factory conditions depend on the selected equipment model and configuration. Common requirements may include:
● Suitable floor space
● Equipment access and safety clearance
● Electrical power supply
● Cooling water
● Process gas supply

Yes. Training can be adapted to the experience level of the customer’s team.
For teams without previous coating experience, training can begin with vacuum fundamentals, equipment operation, product preparation, loading methods, process control, quality inspection, and basic troubleshooting.

Routine maintenance normally includes checking the vacuum system, pumps, seals, cooling system, gas system, coating sources, electrical connections, chamber cleanliness, and consumable condition.
Maintenance frequency depends on equipment utilization, coating process, production environment, and product loading. Operators should follow the maintenance schedule provided with the equipment.

There is no single cleaning interval suitable for every coating system.
Cleaning frequency depends on the coating material, deposition rate, batch frequency, chamber condition, process stability, and accumulated coating residue. Chamber inspection should be included in routine maintenance, and cleaning should be arranged according to actual operating conditions.

Common consumables and spare parts may include:
Coating targets
Process gases
Vacuum pump oil
Sealing components
Heating components
Arc or sputtering source parts
Filters
Sensors
Electrical components
Fixture parts
The required items vary by equipment model and coating process. A recommended spare parts list can be prepared for each project.
