Product Description

The NTP TM450 Automatic Cup Lid Forming Machine represents the next generation of thermoforming technology. Designed specifically for the high-volume production of disposable plastic lids, this "All-in-One" solution integrates material feeding, heating, forming, punching, and scrap winding into a single, compact unit.

Whether you are producing hot coffee lids, cold drink dome lids, or salad bowl covers, the NTP TM450 delivers hospital-grade hygiene and industry-leading precision. It is the preferred choice for manufacturers transitioning to modern, eco-friendly materials like PET and PLA.

1. Precision Forming: The Secret to Leak-Proof Lids

In the beverage packaging industry, the "Snap-Fit" is everything. A loose lid means spills and customer complaints. The NTP TM450 moves beyond traditional vacuum forming by utilizing a Positive & Negative Pressure System. By applying compressed air from above and vacuum from below, the machine forces the plastic sheet into every microscopic detail of the mold.

The result is a lid with:

  • Sharper Undercuts: Ensuring a tight, secure lock on the cup rim.
  • Defined Details: Clear logos and perfectly punched sip holes.
  • Structural Rigidity: Stronger lids even when using thinner materials.

2. Crystal Clear PET & Biodegradable PLA Processing

Processing advanced materials requires precise thermal management. The NTP TM450 is equipped with a German-engineered PID Segmented Temperature Control System. This technology solves the two biggest headaches in lid production:

  • For PET: It prevents crystallization (whitening), ensuring your dome lids remain 100% transparent and premium-looking.
  • For PLA: It provides the gentle, uniform heat required to form biodegradable corn-starch materials without melting or warping.

3. GMP Hygienic Design & Labor-Saving Automation

Food safety is non-negotiable. The NTP TM450 is built to GMP (Good Manufacturing Practice) standards. All parts that come into contact with the product are made from Stainless Steel 304. Crucially, the machine features a "Clean Design" architecture that physically separates the lubrication/drive system from the forming area, guaranteeing zero oil contamination.

To maximize your profit margin, the machine supports full automation integration:

  • Auto-Feeding: Smoothly handles heavy material rolls.
  • Scrap Winding: Automatically collects waste web for easy recycling.
  • Optional Auto-Stacker: Counts and stacks lids directly onto a conveyor, allowing one operator to supervise 2-3 machines simultaneously.

4. Versatile Applications

With a rapid mold change system, the NTP TM450 is versatile enough to produce a wide range of products:

  • Coffee Lids: 80mm / 90mm (PS/PP)
  • Dome Lids: Flat or Arched for Slushies/Smoothies (PET/PLA)
  • Bowl Covers: For Paper Salad Bowls or Soup Containers
  • Mini Portion Cups: Sauce or Condiment lids

FAQ: Cup Lid Forming Machine for PET/PLA/PS | High Speed NTP-TM450

Vacuum forming relies only on suction, which is often too weak for the sharp details required on cup lids (like the snap-fit rim). The NTP TM450 adds "Positive Pressure" (compressed air) from above. This dual-force method pushes the plastic into every corner of the mold, creating a stronger, sharper, and tighter-fitting lid that won't leak.
PET turns white (crystallizes) and PLA deforms if overheated. The NTP TM450 uses a segmented PID temperature control system. This allows you to set precise heating curves for different zones, ensuring the material reaches the exact forming temperature without overheating, maintaining perfect clarity for PET and structural integrity for PLA.
Output depends on the mold layout. For a standard 90mm coffee lid, we typically use a 4-cavity mold. If running at a conservative speed of 25 cycles per minute, your hourly output would be: 4 cavities x 25 cycles x 60 minutes = 6,000 lids per hour.
Absolutely. Leakage usually happens when the cut is not centered or the edge is rough. We use laser-cut steel rule dies combined with heavy-duty guide pillars. This maintains a cutting tolerance of ±0.15mm, ensuring the lid's locking ring is perfectly uniform for a secure snap-fit.
