Manufacture of Wellington Boots
Injection moulding machines for boot manufacture
Hi and welcome to the Boot Kidz, a design company based in London. We've collected videos on the manufacture of Wellington boots.
Wellington Boot Factories
Here's an interesting video showing Nokia wellies from the 1990's ( Part 1, Part 2). Wellington Boots are made all over the world, including China, Eastern Europe, Japan, and even in England. These videos show you how the Wellington boot manufacturing process works. If you're interested in designing your own wellies from scratch then you'll find these videos really interesting. Shoe and boot making is still important today.
Compression molded rubber boots
One process of manufacturing rubber boots is called "compression molding". This forces rubber into a mold in the shape of a boot. If you are interested in making your own boots you should research compression moulding or injection moulding. Making injection moulds is very expensive however. In large quantities this option may be the best though in terms of production output.
Rain Boot/Wellington Boot making machine
This is a rain boot making machine! Amazing technology. Put plastic pellets in one end and out pops plastic rain boots at the other. Incredible. Only weighs 33,000 kgs. Made in iron! Puts a different spin on "make your own rain boots".

Rubber Boots Making - Nokian
A video showing how rubber boots are made. It shows a factory using Desma rubber injection moulding machines. It also shows a Desma reaction injection machine for the production of polyurethane boots (3:41). The first part of the video shows a boot designer drawing the design of the boot on a piece of paper. Measurements are made using a carefully designed model of the boot. Pieces of material are cut out to fit around the model. Rubber is then passed through rollers to soften and flatten. Strips of rubber are extruded out of the last roller. These are passed through more rollers like a spaghetti making machine until the rubber is thin. Dye is added to colour the rubber. The other parts of the boot like the heel, inners, and sole are cut. Tread is added to the sole. The heel is glued to the based of the sole. The factory and conveyor belts show the Wellington boot manufacture process (1:31). The rubber is measured to produce different size boots. The inner lining is glued to the rubber. The boot is placed around a mould and the rubber firmly pressed together using a special tool. The boot is taking shape (2:31). The heel and sole is glued to the boot. The boots are stacked onto a loading trolley and pushed into a large oven for vulcanisation. The finished boots are checked by quality control. Each boot is dipped in silicon to protect the rubber from sunlight. Video ends abruptly at 3:22.
Rubber Boots Factory in Hudong-Zhonghua China
The video starts by showing the outside of the factory. Then it shows the Wellington boots the factory has made. At 1:33 the tour of the inside of the factory begins - first showing the curing ovens and racks of yellow wellington boots/cement boots. The video goes on to show the factory workers creating the white plastic boots which are then covered in a protective yellow cover.

History of Injection Moulding
The American inventor John Hyatt patented the first injection molding machine in 1872. Injection moulding was developed by British Xylonite and was used for making toys in 1941.
L'Aigle Factory Video
It takes 1.2 kg of rubber to make one pair of rubber boots. L'Aigle uses 750 tons of natural rubber per year. It takes 2 years to train someone to make a L'Aigle Wellington boot. Each boot requires 60 assembly steps. L'Aigle produces 4,000 pairs of boots each day. Vulcanisation of rubber occurs at 140 degrees centigrade. All boots are "cooked" at this temperature to cure the latex. Every single boot is checked for waterproofness.
