When you put on an article of clothing, do you ever take a moment to admire the plastic button? Button for clothing have been around since at least the Middle Ages. In addition to serving a functional purpose, they may be used as a stylish accent on clothing. While many are familiar with buttons, few are familiar with their production process.
It is necessary to first grasp the structure of buttons before beginning to learn how to produce buttons. After all, the production process shifts somewhat from one material to another over the course of production. Buttons may be made from various materials, including those found naturally in the environment. Since the beginning of the industrial system in the mid-nineteenth century, plastic has been the potential material for buttons. This trend continued far into the 20th century. They are frequently found on many items, including coats, shirts, and even handmade drafts.
Plastic buttons may be created from various plastics, including ABS, methacrylate (PMMA), polypropylene, resin (polyester), urea, etc. Resin, sometimes known as unsaturated polyester resin buttons, is the material of choice for buttons worldwide. Since it can be mass-produced by machines and is widely used on garments owing to its color, pattern variation, resilience to heat and corrosion, wear resistance, and perhaps other properties. Nevertheless, resin buttons are generally made by pouring liquid polyester, including color and curing ingredients, into something of a chrome-plated kettle before being poured onto enormous revolving metal cylinders. After that, they go through a process of being sliced, polished, drilled, and laser-etched to become buttons.
The current thermoplastic buttons you see in stores start with materials like ABS resin, polypropylene, acrylic, and more. They are categorized as man-made resins. Composite material engineering plastics are widely used because of their resistance against heat, temperature conditions, and chemicals, their malleability, and their high gloss surface.
The mold is the most crucial part of making buttons. Based on the button’s design, the manufacturer will collaborate with the mold maker to create the necessary mold. In addition, we tailor the dimensions and details of each mold set to market needs. It all comes down to the mold regarding how well a button turns out.
If the necessary ABS raw material has been obtained and a mold is accessible, manufacturing may begin.
To begin production, the mold must be mounted on the machine, and the necessary production parameters (such as temperature and pressure) must be established. The ABS material is heated and melted in the barrel in a plastic injection machine. Underneath the pressure of something like the plunger or the screw, the molten plastic becomes squeezed and forced forward, which travels to the nozzle at the barrel’s front. At high speed, it is injected at a lower temperature into the closed mold. The product is removed from the mold once it has cooled and set for a certain time.
