When to Choose DTX-LG, HIWIN, or PMI?

  • When the equipment requires extremely high precision, rigidity, and durability, such as semiconductor equipment, medical devices, or precision measurement systems, HIWIN is recommended.
  • For mid-to-high-end automation equipment, like CNC machining centers, robotic arms, or laser cutting machines, if budget allows and international branding is preferred, choose HIWIN; if you want the same precision with lower cost and shorter lead time, choose DTX-LG.
  • For general industrial automation equipment, such as assembly lines, packaging machines, dispensing machines, or testing platforms, both DTX-LG and PMI are suitable. DTX-LG offers flexible customization and corrosion-resistant finishes, while PMI provides stable performance at a moderate price.
  • For mid-range machinery and equipment, like woodworking machines, printing machines, or conveyor systems, if the customer already uses PMI, continuing with PMI is acceptable; if cost reduction and full interchangeability are desired, choose DTX-LG.
  • For cost-sensitive projects, such as OEM batches, educational equipment, or light-load machinery, DTX-LG is the optimal choice, offering the highest cost-performance and fast delivery.
  • For equipment operating in high-temperature or corrosive environments, such as chemical production lines, outdoor equipment, or food machinery, DTX-LG is recommended, providing multiple anti-rust finishes and optional special materials.
  • When fast delivery or sample validation is required, DTX-LG is the best choice, with direct factory supply, short lead time, and sample availability.
  • For projects requiring long-term mass production with stable supply, both PMI and DTX-LG are suitable, with DTX-LG offering full interchangeability while reducing costs.
