Quanzhou Bayeux Industrial Co., Ltd. is one of the leading manufacturers and suppliers of eva shoe machine in China. With a professional production team, we are able to meet the needs of the majority of our customers. Please rest assured to buy customized eva shoe machine from our factory.
This EVA injection shoe molding machine is primarily designed for manufacturing EVA slippers, sandals, bathroom slippers, rain boots, winter shoes, sports shoe soles, and CROCS footwear. Apart from this, yoga poles, high-speed crash barriers, EVA bags are available too in this machine. One color EVA injection shoe moulding machine can make different styles, sizes, and two color shoes by adjusting mold configurations and changing raw material colors.
What is the production capacity of this EVA injection shoes machine?
Our machine have four design: two station, four station, six station, eight station, different station machine have different production capacity. For example, two-station machine features two workstations and one single injection screw; each workstation can accommodate two sets shoes molds, each set shoe mould could place two pairs of shoes in either identical or different sizes, one hour shoes output is 12–60 pairs. Once the EVA shoe molds are installed and EVA raw material is prepared, the machine initiates automated sequential production, the foaming and heating time for both EVA slippers and their shoes soles is from 180-300 seconds, shoes output in one hour is approximately 30–40 pairs. So according to this machine working production capacity, two-station EVA injection shoes machine is a perfect option for small-scale factory or family-run workshops.
Compared with two-station EVA injection shoes machine, six-station EVA shoes injection making machine is designed for medium and bigger-sized factories. Equipped with two injection screws and six processing stations, each station can accommodate two molds, totaling twelve molds. Each mold can produce two pairs of shoes in either different or identical sizes, significantly enhancing production capacity-ranging from approximately 60 to 240 pairs per hour. EVA slippers like CROCS-style footwear, one hour shoes output is about 160–240 pairs, but EVA rain boots and winter shoes require longer processing times and raw material, one hour shoes output is around 30–50 pairs per hour. After worker installing the EVA shoes molds and preparing the EVA raw materials, operators can configure heating time and material quantities via EVA injection shoes machine's PLC system, enabling continuous automated production. One EVA injection shoes machine need two team, one teams two- four workers .
We recommend that investors start by purchasing one set six-station EVA injection molding machine, after they are familiarize themselves with the production process, then gradually expand their factory scale by adding additional machines. A medium-sized EVA slippers factory typically requires 4–8 sets shoes machine, while a large-scale factory may need 20–40 set shoes machine.
What are the specifications of this machine? What are the main electrical component brands used?
This machine is primarily controlled by servo motors to conserve electricity, with PLC modules from Siemens or Omron brands that precisely regulate critical parameters such as injection volume, temperature, and pressure, ensuring stable product quality and enabling automated, networked management.
The hydraulic system of this machine employs four balance cylinders, delivering a mold-closing force of 180 tons. Through the coordinated operation of proportional control valves and metering pumps, it precisely controls injection volume and pressure with an accuracy of ±2‰. Servo motors automatically regulate motor speed to achieve demand-based oil distribution, saving 30–50% of energy consumption. The thermal pressing system consists of two components: material tube heating (via screw) and mold heating plates. It utilizes a remote digital control module; the material tubes typically employ a four-stage PID temperature control system to ensure stable plasticize and strong resistance to disturbances, achieving a temperature control accuracy of ±0.3°C. Upon mold installation, the heating mode is activated for approximately 30 minutes, during which the material tubes are fully heated before raw materials are automatically fed into the mold for heating and molding. These two systems work in synergy, complemented by PLC-based control coordination, to enable efficient, precise, and automated production in EVA injection molding machines.

What raw materials are required for this EVA injection molding machine?
The primary raw materials for this EVA footwear machine include EVA plastic granule, EVA foam materials, modified EVA raw materials, and EVA materials which mixed with rubber. The equipment enables to use different formula raw material to make different styles shoe, as well as different color materials for making male and female designs. The injector screw is a core component of this EVA shoe molding machine, serving to pump raw material, melt, mix, and metering EVA materials before injecting, at last melting into the mold. To meet requirements for wear, corrosion, and high-temperature resistance, the screw is typically manufactured from high-quality alloy steel and subjected to surface hardening treatments-such as nitriding-to ensure durability under demanding operating conditions. Its segmented, precision-engineered design ensures efficient and stable plasticize of EVA foam materials with diverse properties.
EVA raw material whose full name is Ethylene-Vinyl Acetate, the vinyl acetate content (8%–40%) in EVA particles directly determines the performance of the final product, which have several characteristics style as follow:
Low vinyl acetate content (8%-18%): High hardness, suitable for sports shoe soles and slippers.
Medium vinyl acetate content (19%-28%): Combines elasticity and flexibility, suitable for packaging linings, slippers, sandals, and CROCS footwear.
High vinyl acetate content (over 28%): Excellent softness, widely used in medical products
- EVA products containing foaming agents are commonly used for cushioning packaging, slippers, and sandals.
- Flame-retardant modified EVA material is suitable for protecting electronic components.
- High-transparency EVA particles are primarily used for lining high-end gift boxes.
What type of shoe mold does this machine require? How do I replace the mold?
If you are a slippers manufacturer
You need to purchase EVA slippers molds, EVA CROCS molds, EVA shoe sole molds, and EVA sandals molds.
If you are a Russian rain boot manufacturer
you need to purchase EVA rain boot molds and EVA cotton shoe molds.
If you are a sports shoe manufacturer
you need to purchase shoe sole molds.Of course, you can produce any of the aforementioned shoe types as long as the mold dimensions match our machine's hot plate specifications. All EVA sandals molds, EVA rain boots molds, EVA winter shoe molds, and EVA CROCS molds, EVA slipper shoe mould can be manufactured on our EVA shoes injection machine.
Different shoe types require different shoe molds, and the mold replacement process takes approximately 10 minutes. Pause the machine, use the control buttons to open the safety doors at each station, push each mold (each weighing about 90–100 kg) forward with a cart, insert it into the machine, secure the mold base plate, and then start heating. Our machine's heating plate measures 290×550×250 mm; any mold whose dimensions and height fall within this range and match our mold locking slots can be manufactured on our equipment.
What is the quality of shoes produced by EVA injection molding machines?
By combining the use of machinery, molds, and raw materials, it is possible to produce slippers, sandals, beach shoes, and casual footwear with quality comparable as Crocs shoes; the shoes feature precise sizing and consistent quality, with a scrap rate controllable at approximately 3%–5%.
How to operate and maintain an EVA shoe machine?
Thoroughly clean the machine equipment:
(1) Clean the equipment thoroughly, blow out and remove dust and debris from the electrical cabinet, secure it properly, and wipe off any dust from the solenoid valve.
(2) All moving parts of the machine shall be thoroughly wiped clean with cloth and lubricated with oil for rust prevention (e.g., pull rods, linear guides, piston rods, wear-resistant steel belts, etc.).
(3) Clean debris and oil stains from the hinges and the lower frame beneath the locking mechanism of the cleaning machine to ensure lubricating oil flows smoothly into the waste oil tank, thereby maintaining workshop cleanliness.
Screw Maintenance:
(1) When the plastic material of the product has high viscosity and is prone to decomposition, the screw should be cleaned with PP or PE plastic. After thorough cleaning, any residual material must be removed, and the screw should be withdrawn a certain distance; it must not be stopped at the zero position. (Examples: PC, PMMA, PA, PVC, PEI, etc.)
(2) If plastic residue is attached to the heating ring of the barrel, remove it thoroughly; wipe the hopper clean and close the lid tightly to prevent debris from entering the discharge opening.
(3) Inspect the window glass at the screw connection for integrity; replace it if damaged, and clean dust and oil deposits from the hydraulic cylinder to ensure cleanliness of both the screw and the injection cylinder.
Maintenance of the cooler
Disassemble the cooler, remove scale and debris from its interior, and blow out any remaining water using compressed air to prevent rusting of copper tubes. Particularly for customers in northern regions or areas with temperatures below freezing, ensure all residual water in the pipes, drainage system, cooler body, cooling rings, and molds is completely drained to avoid ice formation-induced damage.
Conduct a thorough cleaning of the factory to ensure its cleanliness and orderliness. Implement rodent prevention measures, as statistics indicate that many customers' machinery has suffered electrical wire damage due to rodent infestation during holidays.
During monthly shift changes, a comprehensive inspection and maintenance of the machinery must be performed.
1. Check whether the machine's emergency stop button is functioning properly.
2. Check whether the fuel level in the tank is sufficient; it should be at least two-thirds above the fuel gauge mark.
3. Check whether the electrical wires and signal cables are loose or damaged by rodents.
4. Check whether the lubricating oil pump is functioning properly, and verify that the lubricating oil lines are neither broken nor loose; perform 2–3 cycles of lubrication to ensure adequate oiling of the machine joints.
5. Maintenance of adjustment wheels: The mold station must be serviced monthly by applying lubricating oil to the mold adjustment mechanism and performing multiple rounds of mold adjustment.
6. Check whether the coolant and cooling water in the radiator are functioning properly.
7. Check whether the mechanical safety devices, limit switches, and proximity switches are functioning properly.
8. Check whether the electrical box and motor fans are functioning properly.
9. Check the oil pressure system (oil pump, oil lines, hydraulic valves) for any oil leaks.
10. Check whether the machine pressure and flow rate are normal.
