Modern footwear manufacturers use various types of plastic shoe making machines for mass production. The plastic footwear machines can make all kinds of shoes using various types of plastic materials. Some of the key types include:
Injection Molding Machines
The injection molding machines create shoes by injecting molten plastic into cooled molds. The molds are made into the exact shape of the shoe design. This machine is mostly used to produce complex shoe parts, like the sole. Fast production is possible, and machine operators can create shoes with precise designs and good quality.
Rotational Molding Machines
Rotational molding machines make shoes by rotating heated plastic around a mold in two parts. This heat causes the material to cover the mold evenly, creating the shoe shape. The shoes produced by these machines are lightweight and have a higher quality than those produced using the injection mold machines.
Suction Molding Machines
The suction molding machine uses air pressure and suction to carefully shape heated plastic sheets into shoes with detailed and intricate designs. These machines use a mold to pull the heated plastic over and into the shape of the mold using suction. The machines are used to mass-produce plastic shoes with smooth surface details.
Blow Molding Machines
In this machine, plastic is first heated and then formed into a parison. The parison is then expanded to fit into a cooled mold cavity using air pressure. This method is mostly used to create hollow and lightweight plastic shoe parts. It is very ideal for making shoe components like transparent soles or cleats.
Production capacity:
The production capacity of a plastic shoe-making machine refers to the number of shoes that the machine can produce within a specific time frame. Different machines have different production capacities. Some machines can produce 50 to 100 pairs of shoes an hour, while more giant, faster machines might make over 500 pairs in an hour.
Types of shoes:
Plastic shoe-making machines can create various types of shoes. Some machines are designed to produce flip-flops and slippers exclusively. Others might be able to make a wider range of shoes, including athletic shoes, casual sneakers, and more, by using different molds and materials.
Shoe parts:
A plastic shoe-making machine can make several parts of a shoe. It could produce the sole, which is the bottom part of the shoe that touches the ground. Some machines might also make the upper part of the shoe, which covers the top and sides of the foot. Advanced machines might be able to create complex shoe components, like the midsole, which is between the sole and upper, as well as other integrated parts like cushioning and arch support.
Material compatibility:
Plastic shoe-making machines work with certain types of plastic. Some common materials include PVC, which is a flexible and strong plastic, TPR, which is similar to rubber plastic and feels soft, EVA, which is lightweight and often used for cushioning, and rubber, which is stickier and more durable. Each machine can handle different kinds of plastic, so it's essential to pick the right material for the shoe.
To ensure that the plastic shoe-making machine runs smoothly and lives a long life, it needs regular maintenance. Here are some essential maintenance tips:
Routine Cleaning:
It's essential to clean the shoe-making machine regularly. Operators should remove any leftover plastic from the last production. They can use a soft brush or cloth to clean the machine parts carefully. Regular cleaning can stop plastic residue from piling up and keep the machine working well.
Lubrication:
Check the instruction manual to see where grease or oil needs to be applied. Lubricate the moving parts, like chains, gears, and guide rails, with the right amount of lubricant. Operators should wipe off any extra oil to avoid attracting dust. Regular lubrication can decrease friction and keep the machine running smoothly.
Parts Inspection:
Regularly inspect crucial parts, such as molds, heating elements, and cutting tools. Look for signs of wear, damage, or deposits. Clean, repair, or replace parts that need attention to maintain consistent product quality.
Regular Maintenance:
In addition to routine cleaning, scheduled machine maintenance is also necessary. Set a maintenance plan based on usage and the manufacturer's instructions. This plan should include timely mold cleaning, lubricant replacement, electrical system inspection, and more. Following the maintenance timetable keeps the machine in good condition.
Operating records:
Maintain a record of the machine's operating conditions. Note the production volumes, material usage, and any issues or repairs encountered. This recorded data is helpful for future analyses and troubleshooting, so it is also essential to keep proper operating records along with machinery maintenance.
