Heel Counter Eversion Shaping Machine for UGG, Sport & Safety Shoes
PLC-controlled machine for the back part eversion pre-forming process of UGG shoes, sport shoes, and safety shoes. Cold-shaping lasts adapt forward eversion for easier upper seating. Aluminum alloy molds deliver fast heating and long service life. 2000 pairs per 8-hour shift.
Why Choose Our Heel Counter Eversion Shaping Machine
Forward Eversion Last Design
Cold-shaping lasts adopt forward eversion, making it convenient to put on and insert the upper. The last shape matches the shoe's back part to achieve a more beautiful, consistent shape after shaping.
Aluminum Alloy Mold & Rubber Mold
Heating head adopts aluminum alloy mold and rubber mold. This combination provides fast heating speed and longer mold service life compared to conventional mold materials.
PLC Control & Computer Screen
Computer screen and PLC control deliver a higher degree of automation and intelligence. 2000 pairs per 8-hour shift production capacity for medium to high-volume shoe factories.
About This Heel Counter Eversion Shaping Machine
Our heel counter eversion shaping machine is mainly used for the back part eversion pre-forming process of various leather shoes, sport shoes, and safety shoes. The process binds the counter, main heel, and lining together to basically reach the shape of the shoe's last back part before the lasting operation begins.
The heel counter is the stiffening component at the back of a shoe that maintains the shoe's shape, supports the heel, and resists collapse during wear. In UGG-style boots, sport shoes, and safety footwear, the heel counter must be shaped precisely to match the last. If it is not pre-formed correctly, the lasting operation becomes difficult, the back part may wrinkle, and the finished shoe may not hold its shape.
The cold-shaping last on our machine adopts forward eversion, making it convenient to put on and insert the upper. By pre-forming the heel counter and back part before lasting, the machine helps the upper maintain its shape, reduces the difficulty of the subsequent lasting operation, and improves the overall appearance of the finished shoe.
The heating head adopts an aluminum alloy mold and rubber mold, which provides fast heating speed and longer mold service life. The aluminum alloy conducts heat efficiently, reaching the shaping temperature quickly, while the rubber mold contacts the upper with the right combination of pressure and compliance to avoid marking or deforming the material. The computer screen and PLC control deliver a higher degree of automation and intelligence, making the machine suitable for production lines requiring consistent, repeatable back part shaping.
How the Back Part Eversion Shaping Process Works
The heel counter eversion shaping operation follows a defined sequence that prepares the shoe upper for lasting. Understanding each step helps operators achieve consistent results.
Upper Loading
The shoe upper is positioned over the cold-shaping last. The forward eversion design makes insertion easy and keeps the back part aligned with the mold.
Counter, Heel & Lining Alignment
The counter, main heel, and lining are brought together and aligned against the last back part. This determines the final back part shape of the shoe.
Heat & Press Shaping
The aluminum alloy heating head presses against the back part, applying controlled heat and pressure to bind the layers and set the shape.
Cooling & Unloading
The shaped back part cools and holds its form. The upper is removed and transferred to the lasting line with a consistent, pre-formed heel counter.
Quality Points for Consistent Heel Counter Shaping
The quality of the shaped heel counter affects the lasting operation, the finished shoe's appearance, and its fit and durability. The following quality points are key to consistent results.
- Last shape matches the shoe design. The cold-shaping last must match the shoe's back part shape. A mismatched last will produce a heel counter that does not fit the upper correctly, causing wrinkles or gaps during lasting.
- Counter material positioned correctly. The heel counter material must be centered and aligned with the last before pressing. Misalignment results in an asymmetric back part that affects fit and appearance.
- Heating head temperature and pressure. The aluminum alloy mold must reach the correct shaping temperature, and the pressing pressure must be sufficient to bind the layers without deforming the upper material.
- Lining and main heel bonded evenly. The counter, main heel, and lining must be bonded together across the full contact area. Partial bonding leaves air gaps that can cause the back part to separate or collapse during wear.
- Cooling before unloading. Removing the upper before the shaped back part has cooled can cause the heel counter to lose its shape. Allow sufficient cooling time before unloading.

Applications
UGG & Boot Manufacturing
Back part eversion pre-forming for UGG-style boots and other footwear with defined heel counter structures. Prepares the upper for lasting with a consistent back part shape, which is particularly important for boots where the heel counter must hold the shaft upright.
Sport Shoe Production
Heel counter shaping for athletic footwear. Binds counter, main heel, and lining together before lasting to maintain upper shape and reduce lasting difficulty. Suitable for running shoes, trainers, and casual sport shoes.
Safety Shoe Manufacturing
Back part pre-forming for safety shoes and work boots. The forward eversion last design accommodates the reinforced heel structures common in protective footwear, where the heel counter must support additional weight and impact.
Leather Shoe Production
Suitable for various leather shoe constructions requiring heel counter pre-forming. The aluminum alloy and rubber mold heating head provides fast, consistent heating without marking or deforming the leather surface.
How to Choose the Right Configuration for Your Factory
The heel counter eversion shaping machine is configured around your shoe design and production requirements. The following factors determine the right specification.
Shoe Type and Last Shape
The cold-shaping last and mold are manufactured to match your shoe's back part shape. Different shoe types-UGG boots, sport shoes, safety shoes, and leather shoes-require different last profiles. Provide your shoe design drawings or existing lasts when requesting a quotation.
Heel Counter Material
The heel counter material (thermal plastic sheet, leather board, or composite) affects the shaping temperature and pressure. Tell us the material type and thickness so we can recommend the correct heating parameters.
Production Capacity
The standard configuration delivers 2000 pairs per 8-hour shift. If your production volume is higher, we can discuss configurations with increased capacity or multiple shaping stations.
Factory Layout and Line Integration
The machine dimensions are 1.74 × 1.03 × 2.0m. Verify that the machine fits your production floor and that it can be positioned upstream of the lasting line. Air supply and power requirements (0.5MPa, AC 380V/50HZ) should be confirmed before installation.
