Double Head Hydraulic High Frequency Embossing Machine

Product Introduction

When shoe material factories mass-process PU upper embossing and automotive interior factories make seat cover embossing, they often face problems such as low efficiency of single-head equipment, long manual mold adjustment time, uneven depth of embossed patterns or blurred edges, leading to high rework rates of finished products and delayed order delivery. The Double Head Hydraulic High Frequency Embossing Machine adopts a pure hydraulic drive and dual-head alternating operation design, combined with a stable high-frequency band of 27.12MHz. It enables materials such as leather and PU to be quickly shaped in a high-frequency electromagnetic field. With precise pressure adjustment (maximum 1T), the embossed patterns are three-dimensional, clear, wear-resistant and not easy to fall off. The equipment is also equipped with a high-sensitivity spark suppression system and high-frequency shielding device, which not only protects molds and materials but also avoids interfering with surrounding equipment, helping enterprises improve the efficiency and quality of mass embossing.

Product Features

Precise Texture Replication, Excellent Texture: For complex textures such as rhombus patterns and litchi patterns, hydraulic constant pressure output and high-frequency constant temperature shaping ensure the pattern depth error is ≤0.05mm, with sharp edges and no virtual edges. Leather fibers are not damaged, the touch is soft and the shaping is long-lasting, meeting the texture requirements of high-end shoe materials and automotive interiors.

1000 Groups of Parameter Memory, Fast Style Change: The 7-inch PLC system can store 1000 groups of embossing parameters for different materials and patterns. One-key parameter retrieval during style change eliminates repeated testing, reducing debugging time from hours to within 3 minutes, greatly reducing material waste and adapting to small-batch and multi-style orders.

Intelligent Mold and Material Protection, Easy Operation and Maintenance: The 0.1-second response spark suppression system + automatic mold level calibration function can avoid sparking and material damage caused by unstable current or mold deviation, extending the mold service life by more than 30% and reducing later maintenance costs.

Green and Low-Consumption Design, Strong Compliance: The high-frequency shielding device ensures the equipment radiation is far below the industrial safety standard; the energy consumption of dual-station alternating operation is 25% lower than that of single-head equipment, balancing production efficiency and green manufacturing needs.

Application Scenarios

Mass Embossing of Leather/PU Shoe Materials: Targeting the needs of three-dimensional patterns on shoe uppers, non-slip textures on insoles, and pattern forming of watch straps, it solves the pain points of low efficiency and uneven embossing depth of traditional single-head equipment. Through dual-head alternating operation, the equipment improves production capacity; precise pressure control ensures strong consistency of embossing for shoe uppers of different sizes, and the patterns are wear-resistant and not easy to deform, helping shoe factories reduce rework rates and shorten delivery cycles.

Leather Embossing for Automotive Interiors: Suitable for embossing decoration processing of car seat covers, steering wheel covers, and sun visors, solving the problems of uneven pressure in manual embossing and easy falling off of patterns. With the stable pressure of pure hydraulic drive and high-frequency shaping technology, the embossed patterns are clear and three-dimensional, and can adapt to automotive interior leather of different thicknesses, meeting the strict quality requirements of automobile manufacturers for interiors.

FAQ

1.Can the complex rhombus pattern embossing achieve consistent depth for every texture?

Answer: Yes, the equipment uses hydraulic constant pressure output and high-frequency constant temperature shaping, ensuring the pattern depth error is ≤0.05mm. Even for complex rhombus patterns, the texture of the entire surface can be uniform, meeting the texture requirements of high-end products.

2.For multi-style orders with frequent mold changes, do parameters need to be re-adjusted when retrieved?

Answer: No re-adjustment is needed. The PLC system can store 1000 groups of parameters. One-key parameter retrieval during style change, combined with quick buckle mold change, can complete switching within 3 minutes, greatly reducing test run waste.

3.When embossing microfiber leather, sparking is easy. Can this equipment avoid it?

Answer: Yes, it can effectively avoid sparking. The equipment is equipped with a 0.1-second response spark suppression system, combined with automatic mold level calibration function, which can quickly cut off abnormal current, prevent microfiber leather from being damaged by sparking, and protect the mold at the same time.

4.Does the equipment radiation value meet EU environmental standards?

Answer: Yes, it meets the standards. The equipment has a built-in high-frequency shielding device. Tested, the radiation value is far below the EU industrial safety standard.

5.What is the folding resistance of embossed leather?

Answer: The folding resistance of embossed finished products is ≥5000 times. Adopting the "molecular heat sealing + hydraulic shaping" process, the pattern is closely integrated with the leather substrate, which is not easy to fall off or crack after repeated folding, meeting the industry durability requirements.

6.For embossing leather of different thicknesses, do I need to manually adjust the electrode height?

Answer: No manual adjustment is needed. The equipment supports automatic adaptation of electrode height. According to the set material thickness parameters, the electrode can be quickly and accurately positioned without manual intervention, improving operational convenience.

7.If the mold is worn after long-term use, will it affect the embossing accuracy?

Answer: No, it will not. The equipment is equipped with a mold wear compensation function, which can offset the accuracy deviation caused by mold wear through parameter fine-tuning, without frequent mold replacement, reducing the use cost.

8.When two stations emboss different patterns at the same time, will the parameters interfere with each other?

Answer: No interference. The two machine heads support independent parameter storage, and can set pressure, temperature and time separately. When processing different pattern products synchronously, the parameters do not interfere with each other, adapting to the needs of mixed orders.
