The Step-by-step Process on Manufacturing Rain Boots

Rain boots are made typically from rubber or polyvinyl chloride (PVC), and their sole purpose is to help people have a comfortable walking experience during the rainy season. Because of them, many people don&#;t have to worry about falling or getting stick into mud and soil whenever going out.

In the modern-day, rain boots are manufactured not only for foot protection but also as part of a fashion statement. So if you are residing in the rain prone region, then it would be best to incorporate rain boots into your style. Whether you favor wearing skirts, jeans, or shorts, rain boots can easily be associated with your wardrobe.

Wanna know how rubber rain boots are being made? This page will discuss fascinating steps on making handcrafted rubber rain boots and its laborious process that requires multiple handling of tools and components.

1. Mixing the Main Components

The natural rubber is mixed together with other components, namely carbon black, fillers, oil, and curatives. They are fused either in an open-top mill or enclosed mixing machine. Precise measurement is extremely essential in the stage of weighing out the ingredients to guarantee that the preferred physical properties of the mixture are attained.

When the compound has been mixed, then it is needed to &#;settle&#; by storing it. Before storing, the mixture is tested first to assure that it passed the pre-determined specifications. Then from the store, the uncured rubber is sent to four minimal pre-processing stages before it reaches the assembly stage.

2. Molding of the Heel

In this stage, the rainboot heel is molded through compression. This is accomplished through placing a tiny piece of pre-weighed uncured rubber or called a slug into a mold cavity that is then compressed under high pressure and simultaneously heated.

3. Outsole Calendering

The sheets of uncured rubber or pigs are drawn from the store and heated up on a mill to prepare them to be soft. Once they reached the required smooth and soft texture, they are then fed through the outsole calender.

A calender is formed by a series of metal rollers that process uncured rubber to a specific gauge and roll a pattern onto the surface of the rubber. Heated knives are used to carve out the wanted sole size in the aftermath of cutting around the template.

4. Upper Calendering

As mentioned earlier, the pigs from the store are heated up on a mill and dispensed in the upper calender. The &#;upper&#; part relates to the thin external layer of rubber on the rain boot. Not like the &#;outsole&#; part, which leaves a perfectly smooth finish on the rubber&#;s surface.

As the rubber is being fed into the calender, a continuous thin sheet is wound up onto drums. Then different parts are cut out from the continuous layer of the upper rubber.

5. Skimming and Friction Calendering

The term skim refers to the canvas lining inside the rain boot. It has a coat of rubber skimmed onto the surface that creates a solid bond with other rubber elements. On the other hand, the term friction pertains to the process of weaving rubber canvas for a reinforced internal layer.

This process is different from calendering due to the layers of the canvas that is dispensed into the first two rollers, whether it is &#;skim&#; or &#;friction&#;. The skim or friction is then rolled onto the drums. Afterward, different parts are sliced out from the continuous rolls of skim or friction through a clicking machine.

6. Assembling of Boots

In this phase, the assembly line workers build up the rubber boots layer by layer, entirely by hand. The assembly chain is a long slender table that has a chain rotating around the outer side with lasts sticking up in the air. It stops for a limited time at each station where an individual is situated to do a specific task.

A last is a mechanical shaped form of the human foot that is used for boot sole molding operations. Every pair of rain boots is assembled on a last and is completed by laying the successive coatings of skim, friction, uncured upper rubber components, and the likes up to the part where sole and heel are attached. Since the rubber is uncured, it is deemed adhesive. Therefore, once it is laid at the preferred position, it stays and plastered there. 

7. Vulcanization

In this stage, the lasts are removed from the assembly chain and packed on a boot trolley. The group of rain boots is shoved into a large oven called a vulcanizer where they are cured by heat and pressure. Once the process is done, the boot trolleys are removed, and the rain boots are pulled off once the aluminum lasts have cooled down.
