Xin xiang Ceramic Mug Manufacturer, In recent years, cork-bottomed ceramic coffee mugs have quietly emerged. It is a perfect blend of "porcelain" and "wood". Porcelain coffee cups and handles with brown wooden mugs. It gives us another kind of indescribable cosiness when enjoying our coffee. This cork-bottomed coffee mug is only known to us through gift shops or on Amazon. So, how is she produced by the ceramic mug factory?
Cork bottom ceramic coffee mug, she is actually composed of two parts: ceramic coffee mug and cork mat. First of all, let's introduce what cork bottom is.
1. Cork introduction
Cork, commonly known as water pine, cork, cork bark, is a tree tissue. It is commonly used to make floats, shoe inserts, corks, mugs, etc.
The growth of cork, difficult to adapt to the high temperature and high temperature climate, generally grows in the subtropical and temperate zones, the altitude of 400 - 2000 metres in the mountain forest. Common producing areas in the world are: Portugal, Spain and China. Our country's main producing areas are concentrated in: Sichuan, Shaanxi, Henan and Hubei.
Cork consists of many flat cells arranged in a radial pattern. Cell cavities often contain resin and tannin compounds, the cells are full of air, so cork is often coloured, light and soft, flexible, impermeable to water, not easily affected by the action of chemicals, and is a bad conductor of electricity, heat and sound. Composed of 14-sided dead cells, radially arranged with each other in a hexagonal prism. Typical cell diameter is 30 microns and cell thickness is 1 to 2 microns. There are ducts between the cells. The interval between two adjacent cells consists of five layers, two of which are fibrous in nature, followed by two layers of corky layer, right in the middle of a layer of wood, every 1 cubic centimetre in more than 50 million cells.
2. Cork properties
This structure makes the cork skin has very good elasticity, sealing, heat insulation, sound insulation, electrical insulation and friction resistance, plus non-toxic, odourless, small specific gravity, soft touch, not easy to catch fire and other advantages, there is still no man-made products comparable to it. In terms of chemical properties, several hydroxy fatty acids and phenolic acids formed by the ester mixture is a characteristic component of cork, collectively known as cork resin.
These substances are resistant to decay and chemical attack, so in addition to concentrated nitric acid, concentrated sulfuric acid, chlorine, iodine and other corrosive effects, water, grease, gasoline, organic acids, salts, esters, etc., do not have a chemical effect. Wide range of uses, such as cork, refrigeration equipment, insulation layer, life buoys, sound insulation boards.
3. Cork bottom production
After steaming, softening, drying, direct cutting, stamping, whirling and other methods to make finished coasters, and coffee cups assembled to form: cork bottom ceramic coffee cups.
Above understand what cork bottom, ceramic mug production process, I often introduced before. Then, I will simply repeat it again today.
4. The production of ceramic mugs
According to the size of the customer's customised mug capacity and the shape of the coffee cup, our engineers have to break down the requirements and work out the raw material ingredients (detailed description of the ingredients of ceramic coffee mugs) and weight.
4.1.Blank production. Workshop workers will put the adjusted blank clay into the making machine. The machine will divide the blank clay according to the instructions set by the engineer and then make the moulding of the blank body. The handles of the mugs usually need to be made separately and assembled and moulded later.
4.2.Assembly. The pressed blank needs to be left for 5-10 minutes for the blank to harden. Remove the mug handle after it has solidified and moulded. Firstly, flatten the ends of the mug handle, then correct the excess clay on the handle. Finally, holding the mug handle and dipping it in the clay, the handle and the mug are glued together to form a complete ceramic mug. It takes about 20-30 minutes to dry the completed mug (increase the blowing force and temperature to speed up the drying process).
4.3. Repair. After drying ceramic mugs need to trim and wash. The purpose is to remove the protruding particles on the surface of the mug and to smooth the bottom of the mug. After trimming and washing the mugs, the final drying process takes place. This takes about 10 hours until all the water in the mug has evaporated.
4.4. Glazing. The completely dried mugs are glazed. There are many types of glazes (Glaze composition and classification). For the glazing session, the simplest is a single-colour glaze, in which the whole of the moulded mug is placed in the glaze. If the mugs need multiple glaze colours, then the operation is a bit more complicated. Nowadays, our factories are using fully automatic machines to glaze. After drying, the mugs are placed on a conveyor belt, and the machine transports the mugs to the glaze pool and glazes them automatically.
4.5. After the glazed mugs are dried, they can be fired in the kiln. If you need to decal, that is, the customer custom LOGO or pattern. In this part, you can decal (detailed decal types and techniques see: Decal paper categories and decal techniques for ceramic coffee mugs). In addition, depending on the colour of the mug, there are high temperature firing, medium temperature firing and low temperature firing.
The mug is made after the above process. Assemble the cork base and coffee mug together, it is your customised cork base ceramic coffee mug. After a series of inspections, the qualified products will be safely packed (How to pack the ceramic mug so that it will not be damaged?), the exquisite cork bottom coffee mug will be able to come to your hands across the ocean.
