• 🌡️ Temperature Control System: Constant‑temperature water supply; steel belt and mandrel temperatures digitally displayed

• 🔌 Electrical Components: Major electrical parts from internationally renowned brands for reliable performance

Optional Features:

• Automatic splicing for roll changeover

• Continuous operation during roll change (non‑stop winding)

• Automatic compression ratio detection

• Automatic rejection of defective products

Technical Specifications:

✅ This machine utilizes mandrel forming and high-frequency welding technology, with PLC computer control for stable performance, strong welds, and excellent appearance quality.

🔧 (B) 80‑Ton Rotary Vertical Injection Molding Machine – Tube Shoulder Molding (Fomtec)

After the tube body is produced by the extrusion machine, the tube shoulder is molded and bonded to the body through the shoulder injection molding process. The Fomtec 80‑Ton Rotary Vertical Injection Molding Machine serves as the core shoulder molding equipment in this production line:

Model Positioning:
Fomtec designs and manufactures a comprehensive range of injection molding machines covering clamping forces from 15 to 750 tons and shot capacities from 35 g to 8000 g. The 80‑ton model belongs to the FT series (vertical clamping, vertical injection), specifically optimized for tube shoulder molding applications. Founded in 1987, Fomtec has nearly 40 years of professional experience in vertical injection molding and is recognized as a National High‑Tech Enterprise with 105 patents.

Core Advantages:

1. 🎯 Vertical Clamping & Vertical Injection Design – The mold faces upward, allowing intuitive and convenient tube body insertion with a clear view for the operator – ideal for precision tube shoulder molding.

2. 🎛️ Multi‑Stage Pressure & Speed Control – Injection and clamping are controlled by multi‑stage pressure and speed settings, adjustable according to product requirements, ensuring consistent weight, appearance, and sealing performance for every tube shoulder.

3. 📊 LCD Display + Parameter Storage – The LCD screen clearly displays all functions and stores multiple molding parameter sets. Parameters for different tube specifications can be recalled with one touch, dramatically reducing mold changeover time.

4. 🌡️ High‑Precision P.I.D. Temperature Control – Stable temperature control across all zones with minimal deviation, ensuring consistent and reliable tube shoulder quality.

5. 🔩 Optimized for Tube Shoulder Molding – Tube shoulder molding machines typically require clamping force of 40–60 tons and shot capacity of 80–120 g. The 80‑ton model provides additional clamping force margin for larger tube diameters or higher cavity counts, with clamping force covering 15–750 tons – offering ample room for future product range expansion.

6. 🔄 Rotary Structure – Seamless Line Integration – The rotary table/turret design enables automatic handling of tube bodies through the continuous cycle of insertion → injection → extraction. Integrated with the full-line automation system, one injection molding machine can automatically accept tube bodies from the extrusion machine, achieving fully automatic operation covering tube feeding → orientation recognition → insertion → injection → extraction.

🖨️ (C) Offset Printing Machine

After tube body extrusion and shoulder molding, tubes require surface decoration. This production line features a fully automatic offset printing machine (available in 4‑color or 6‑color configurations) for high‑precision printing on the tube body. Combined with an integrated coating and drying unit, it enables continuous printing, coating, and drying operations.

🔒 (D) Capping & Sealing Machine

After printing, tubes require orifice sealing and cap application. The production line includes a fully automatic capping and sealing machine (available in combined configurations for punching, sealing film application, and capping), which automatically performs orifice sealing and cap screwing.

🎯 IV. Complete Line Technical Advantages

🤖 1. Fully Automated Continuous Production

The entire line operates from sheet input to finished tube output in fully automatic continuous production. The extrusion machine and injection molding machine are linked by an automatic conveying system – tube bodies are transferred to the injection molding machine without manual handling. After shoulder molding, tubes automatically enter the printing process, followed automatically by the capping/sealing process. The complete line significantly reduces manual intervention and substantially lowers labor costs.

⚡ 2. High Speed, High Output, High Precision

🎯 3. Wide Material & Product Adaptability

This production line accommodates various materials including all‑plastic sheets, aluminum‑plastic laminated sheets, full‑coverage sheets, and high‑gloss sheets. It covers tube diameters from 12.7mm to 60mm, meeting the diverse tube packaging needs of the cosmetics, toothpaste, pharmaceutical, food, and chemical industries.
