FAQ

Custom Automation Solutions

  • Q What information do you need before recommending a machine?

    A To recommend the right machine configuration, we usually need the product drawing or 3D model, material, blank type, sample photos, annual or daily output target, current machining or assembly process, tolerance requirements, and required automation level. For assembly projects, the component list, assembly sequence, cycle-time target, and inspection requirements are also important.
  • Q Can you provide a complete turnkey solution instead of only one machine?

    A Yes. We can provide a complete solution according to the customer's product, process and capacity target. The scope may include process evaluation, machine selection, fixture and tooling design, automation layout, installation, commissioning, operator training, spare parts support, and after-sales service. The final scope is confirmed after reviewing the product and production requirements
  • Q Can you help improve the process, not just copy our existing process?

    A Yes. Many projects start with only a product photo or a rough production target. Our engineering team reviews whether the process can be simplified by reducing repeated clamping, combining several operations, changing the feeding method, improving the positioning datum, or using a rotary transfer machine instead of several separate machines.
  • Q Can you provide FOB, CIF or export support?

    A Yes. After the technical solution is confirmed, we can quote under suitable trade terms such as FOB or CIF. We can also support export packing, wooden case marking, shipping documents and coordination with the customer's forwarder or our shipping agent.
  • Q Do you provide installation, commissioning and operator training?

    A Yes. We can provide remote support, on-site commissioning and operator training according to the project scope and destination country. For overseas projects, we usually prepare operation manuals, electrical drawings, spare parts lists, training guidance and remote troubleshooting support.

Rotary Transfer Machine / Waterwheel Machine

  • Q Can you provide technical guidance if we are new to this product?

    A Yes. For new brass fitting or valve manufacturing projects, we can help evaluate the process route, equipment selection, output model, staffing requirement and future expansion direction. At the early stage, we normally focus on confirming the correct machine configuration before discussing broader factory operation details.
  • Q Can the machine include automatic loading and unloading?

    A Yes. Depending on the part shape, blank type and production rhythm, the machine can be designed with manual loading, semi-automatic loading, robotic loading, vibratory feeding, conveyor feeding or customized loading/unloading systems. The loading method must match the required cycle time and product stability.
  • Q Is a rotary transfer machine suitable for very small batches?

    A Usually not. A rotary transfer machine is designed for stable repeated production. For prototypes, small batches or products that change frequently, CNC lathes or machining centers may be more flexible. We evaluate the annual output, product stability and payback before recommending this machine type.
  • Q How do you ensure machining consistency on a rotary transfer machine?

    A Consistency depends on the full machining system, including fixture positioning, clamping stability, spindle rigidity, servo feed control, cutting tools, coolant, chip removal and process sequence. Reducing repeated clamping also helps reduce accumulated positioning error between operations.
  • Q What affects the cycle time of a rotary transfer machine?

    A Cycle time is affected by the longest station process, material, cutting depth, hole size, thread specification, tool life, coolant condition, loading method and inspection requirements. Therefore, cycle time should be calculated after reviewing the product drawing and process route.

Brass Fitting & Valve Manufacturing Solutions

  • Q What should we confirm before quoting a brass fitting project?

    A Before quotation, it is important to confirm the product drawing, material, blank type, required annual output, current or expected process route, tolerance requirements, available workshop space, power supply, compressed air, quality standard and expected automation level.
  • Q For 200,000 pieces per year, should we use CNC machines or a rotary transfer machine?

    A The answer depends on part complexity, cycle time, investment plan and future expansion. For a moderate annual volume, CNC machines may be suitable if the product changes frequently. If the product is stable and the process includes repeated drilling, boring, threading or tapping, a rotary transfer machine or dedicated line may reduce long-term labor and process transfer.
  • Q Does the blank type affect machine selection?

    A Yes. Brass bar material, forging blanks, casting blanks and pre-machined blanks may require different production routes, clamping methods and machine configurations. Bar material may be suitable for bar-fed CNC turning, while forging or casting blanks may require different locating, machining allowance and transfer processes.
  • Q Can you provide a complete production solution for brass fittings or valves?

    A Yes. We can evaluate a complete solution for brass fitting or valve production, including blank preparation, CNC turning, rotary transfer machining, cleaning, inspection, assembly, testing and packaging. The final equipment list depends on the product type, annual output, material, blank form and automation level.

Automatic Assembly Machine

  • Q What is the typical cycle time of an automatic assembly machine?

    A There is no standard cycle time because it depends on the product structure, number of assembly steps, feeding method, inspection requirements and automation level. Simple assembly processes may require only a few seconds per cycle, while more complex products involving multiple components, testing or vision inspection may require a longer cycle. After reviewing the product and assembly process, we can estimate the expected cycle time and production capacity.
  • Q Can one assembly machine handle different product models?

    A Yes, in many cases. The assembly machine can be designed with changeable fixtures, adjustable positioning modules and HMI recipe management for different product models. The feasibility depends on the differences in product dimensions, component structure, assembly sequence and quality requirements. For similar products, changeover can usually be completed by selecting a stored recipe and replacing a few tooling components. For products with significant structural differences, separate fixtures or dedicated assembly stations may be required.
  • Q Can the assembly machine be connected with other production lines?

    A Yes. The machine can be used as a standalone assembly system or integrated into a larger production line. For water meter production, it can be connected with dial installation, meter core installation, laser marking, plug installation, robot handling, carton loading and packaging lines. The integration method will be confirmed based on cycle time, signal interface, safety logic and factory layout.
    • Standalone machine or part of a complete automated line
    • Can communicate with third-party equipment through agreed interfaces
    • Supports future expansion when production volume increases
  • Q How do you prevent missing parts or incorrect assembly?

    A The machine can be equipped with different detection methods according to the risk points of the product. Typical options include optical fiber sensors, photoelectric switches, proximity sensors, part-presence detection, in-position detection, feeding-status detection and optional vision inspection. For press-fitting or tightening processes, force, stroke or torque monitoring can also be considered when required.
    • Detects whether small parts are fed and positioned correctly
    • Checks product in-position status before the next process
    • Optional vision or force-displacement monitoring for higher quality control
  • Q How does an automatic assembly machine reduce manual work?

    A The machine reduces manual work by integrating repetitive assembly steps into one controlled process. Depending on the product, the system can complete automatic feeding, positioning, insertion, press-fitting, tightening, inspection and unloading. Operators mainly handle loading, material replenishment, monitoring and basic production management, instead of repeating every assembly action manually.
    • Reduces repetitive manual placement and pressing operations
    • Improves production rhythm and process consistency
    • Helps reduce operator-dependent assembly variation
