Automatic Lid Making Machine for Manufacturing PP and PET Cup Lids | Thermoforming Line Supplier

🔹 Overview & Application Scope

The YK-TF500PP is a high-efficiency automatic thermoforming machine designed for the continuous production of plastic lids, trays, food boxes, and packaging components.

With a robust servo-driven system and forming area of 460mm × 280mm, it supports multi-cavity mold layouts, delivering reliable output at 15–25 cycles per minute.

✅ Ideal for:

• Cup lids (flat, dome, sip-type)

• Medical trays, pill packaging

• Cosmetic blister packs

• Stationery/electronic/hardware trays

• Food packaging & disposable lunch boxes

🔹 Forming Area & Performance Advantages

• Maximum Forming Area: 460mm × 280mm

• Max Sheet Width: 500mm

• Max Forming Depth: 50mm

This forming zone allows multi-up mold placement, such as 4–6 cavities for 90mm lids or 2–4 cavities for food containers—directly enhancing per-cycle yield and unit cost control.

🟩 Why it matters?

Larger forming area = higher productivity = fewer machine cycles per output volume.

🔹 Supported Materials

• PP

• PET

• PVC

• HIPS

• PLA 

Roll-fed sheet materials (up to 500mm wide) in transparent or colored formats are supported.

🔹 Optimized for PP Lid & Tray Production

The YK-TF500PP is specially optimized for PP (Polypropylene) sheets, making it an ideal solution for manufacturers focused on hot drink lids, takeaway food boxes, and heat-resistant trays.

PP material is lightweight, food-safe, and recyclable—but also requires precise temperature control and stable pressure during forming.

This model features enhanced heating zones, servo-regulated traction, and robust mold compatibility for perfect PP forming results.

✅ High forming accuracy for PP

✅ No deformation under heat

✅ Clean punching edges, ideal for high-speed stacking

✅ Supports transparent, semi-clear, or color PP sheet rolls

Why Choose YK-TF500PP for PP lid making?   ✅ Enhanced heater zones calibrated for PP’s higher softening point ✅ Mold base treated for uniform PP flow ✅ Supports PP thickness from 0.25–1.2mm ✅ Better yield and reduced scrap rate when forming PP over PET

🔍 Frequently Asked Questions (FAQ)

Q1: Can this machine work with PP materials continuously?

A: Yes. YK-TF500PP is optimized for PP sheets with enhanced heating zones, stable forming pressure, and precision mold compatibility. It’s suitable for continuous high-speed production of PP lids, trays, and containers.

Q2: What’s the maximum size of products I can make with this machine?

A: The machine supports a maximum forming area of 460×280mm and a forming depth of 50mm. Depending on the product shape, you can run multi-cavity molds for lids, trays, or shallow boxes.

Q3: Is mold customization supported? Can I use my own lid design?

A: Absolutely. We provide custom aluminum molds based on your CAD drawings or samples. You can also emboss your brand logo directly on the lid.

Q4: How many pieces can this machine produce per hour?

A: With 4–6 cavities per cycle and a speed of 15–25 cycles/min, production can reach 3,600 to 9,000 pieces/hour, depending on lid size and mold layout.

Q5: What additional units can I integrate with this machine?

A: The system supports expansion with automatic stacking, counting, and waste rewinding units. It can also be connected to a downstream packing or labeling line if needed.

Q6: Do you offer overseas support or remote installation?

A: Yes. We provide English manuals, remote video guidance, and on-site installation service through our experienced technical team for overseas customers.
