  BTPL’s Commitment to Innovation and Automation

  Technology is at the core of our identity. Founded on the principle of continuous improvement, we are dedicated to advancing our equipment, processes, and expertise. As a pioneer in automation for insert molding applications, BTPL successfully implemented automated solutions for Battery Lid molds, which led to the development of a twin-cavity tool, significantly boosting productivity.

  To streamline operations, BTPL has integrated an ERP system covering planning, procurement, purchasing, manufacturing, and supply chain management. This ensures a highly professional and transparent ecosystem, providing customers with real-time information while minimizing dependency on human intervention.

  Our capabilities have further expanded with the addition of two all-electric 180-ton machines, enabling the production of high-precision plastic parts while offering substantial energy savings.

  BTPL continues to invest in automation, advanced ancillary equipment, and emerging technologies to achieve unmatched precision in component dimensions, aesthetics, and mechanical properties, while also enhancing overall efficiency.

  To further our automation goals, BTPL employs robotic technology from Switek Inc (PRC). Following the successful deployment of our initial robotic systems, we are now scaling up to automate nearly half of our machines with insert molding capabilities, ensuring mistake-proof production and significant efficiency gains.

• What are the types of sensors used in plastic injection molding?

  • Cavity and hydraulic pressure Sensors –
  • Thermocouples, infrared and melt temperature sensors
  • Waterflow and resinflow sensor
  •  Humidity & Moisture Sensors
  • Vibration & Acoustic Sensors
  • Optical & Vision Sensors
  • IoT & Wireless Smart Sensors

• What are the drying systems used for raw material preparation in plastic injection molding?

  Drying plastic resins are essential for removing problems like bubbles, warping, weak mechanical properties, and surface imperfections.

  The drying systems remove moisture from hygroscopic materials like ABS, PET, Nylon and Polycarbonate. The drying process is done either by heated air, desiccant beads, dry compressed air, infrared radiation, vaccum pressure.

  Dryer Type	Best for	Pros	Cons
  Hot Air Dryer	Non-hygroscopic resins	Low cost, simple operation	Ineffective for moisture-absorbing plastics
  Desiccant Dryer	Hygroscopic materials	Deep drying, precise moisture control	Higher energy use
  Compressed Air Dryer	Small production runs	Low maintenance, energy-efficient	Limited effectiveness
  Vacuum Dryer	High-precision applications	Fast drying, energy savings	High initial cost
  Infrared Dryer	PET, PLA, fast drying needs	Quick processing, efficient	Potential overheating risk
