How to Externally Adjust Ascending and Descending Stop Points in Lasting Machines?

Product Introduction

Guangdong Tenghong Machinery Technology Co., Ltd., founded in 2000 and located in Houjie Town, Dongguan City, China, is a leading manufacturer specializing in high-quality shoes, handbags, leather machinery, and shoe making machine equipment. Among its flagship products is the TH-727MA Automatic Cementing Heel Seat Lasting Machine, designed for efficient and precise heel seat lasting for shoes with lasts up to 180mm in height.

This machine features a fully automatic cementing function that significantly improves production efficiency by saving manual gluing time while ensuring high-quality adhesion. It is widely used in midsole, soft midsole, and heel seat lasting processes, particularly suitable for wall-type and wrapped soles.

The TH-727MA emphasizes precision and durability with its height micro-adjustment structure for lasting height control. It includes a range of complete specifications for scrapers and fasteners that accommodate almost any shoe style. Its innovation focuses on stability through a fully oil pressure system and quick, easy height and position adjustments displayed on a user-friendly touch screen. With a motor power of 2HP and oil pressure of 40kg/cm², the machine can produce up to 2,000 pairs per 8-hour shift, making it a robust and high-performing solution for modern shoe manufacturing.

Product Features

The TH-727MA Automatic Cementing Heel Seat Lasting Machine is built on a fully oil pressure operation system that ensures higher machine stability during operation compared to pneumatic or mechanical counterparts. This oil pressure system controls all movements, especially the ascending and descending actions, creating smooth and consistent force that protects footwear materials from damage while ensuring strong adhesion.

One of the machine's core features is its external adjustment capability for ascending and descending stop points. This feature allows operators to finely tune the stop positions of the heel seat lasting process externally without disassembling the machine. Such adjustability is essential for manufacturers handling various shoe models or changing production requirements. Precise positioning improves product consistency and reduces waste caused by misalignment or glue detachment.

The positioning rod is designed with a micro height adjustment structure, making it easier and more accurate to control the shoe last height during the lasting process. This micro-adjustment ensures that the lasting height is perfect, preventing issues like poorly fitted heels or lasting faults that can degrade shoe quality.

The scraper and fastener system adopts a link-type wrapping structure, providing the best tightening effect and allowing it to suit any shoe type. The auxiliary scraper uses a screw rod design, which enhances structural strength, durability, and allows quick height adjustments. Together, these ensure even glue distribution and secure lasting.

The machine also features a dual-stage pressure design on the inner support table and a matching preheating scraper mechanism. This design effectively smooths the heel and prevents deformation, significantly improving the lasting effect and elevating the quality levels of finished shoes.

PLC-based control with a touch screen displays settings, including the height and stop points of parts to be adjusted externally. By making use of this graphical interface, operators can control and monitor the lasting process conveniently, ensuring seamless changeovers and consistent quality.

Other specifications include a 2HP motor, 1.02kw heating power, a 50-liter oil tank for stable hydraulic operation, and dimensions of 970(L) x 750(W) x 1450(H) mm which fits seamlessly within modern factory setups.

Manufacturing Craftsmanship and Production Advantages

The TH-727MA machine benefits from Guangdong Tenghong's strong manufacturing tradition grounded in ISO9001:2008 quality management. The company integrates advanced foreign technology with rigorous process controls to ensure every lasting machine delivers durable, reliable performance in demanding industrial environments.

The external adjustment for ascending and descending stop points reduces downtime during production changes, simplifying set-up and allowing fast adaptation to different shoe lasts and designs. This flexibility is crucial for manufacturers juggling multiple product lines, enabling higher output without sacrificing quality.

The fully oil pressure system promotes constant, stable force application, maintaining glue adhesion integrity after molding. This dependable operation reduces defect rates, increasing first-pass yield and lowering raw material waste—all essential for competitive pricing and profitability.

Support components like the screw rod auxiliary scraper provide enhanced durability and longevity, cutting maintenance costs and machine downtime. Rapid height adjustment reduces manual labor and training needs, making the production line more agile and cost-effective.

Guangdong Tenghong backs the machine with comprehensive service, including pre-sale plant planning, installation, and after-sales technical support. Such assistance ensures customers can quickly realize the machine’s benefits, reducing the learning curve and optimizing production efficiency.

The robust structure, user-friendly PLC controls, and precise glue application not only improve finished product aesthetics but also increase market competitiveness for Chinese shoe manufacturers internationally.

Conclusion

The TH-727MA Automatic Cementing Heel Seat Lasting Machine epitomizes precision and flexibility in modern shoe making machinery. Its capability for external adjustment of ascending and descending stop points significantly enhances operational control, allowing manufacturers to fine-tune lasting processes easily to accommodate diverse shoe lasts and designs.

By combining stable hydraulic oil pressure with intelligent, user-friendly controls, the TH-727MA ensures superior glue adhesion that lasts beyond molding, reducing defects and increasing manufacturing efficiency. These features translate into cost savings and increased throughput for shoe manufacturers.

As a high-quality product from Guangdong Tenghong Machinery Technology Co., Ltd., a reputable Chinese manufacturing leader, the TH-727MA offers excellent price-performance balance and technical innovation, consistently meeting the needs of modern shoe production.

Investing in this machine means gaining not only advanced technology but also the expert support and service necessary to maintain competitive advantage in today’s footwear market.
