Acrylic bath production process

- Mar 26, 2018 -

Molding: bathtub, shower room chassis, backplanes ware molding usually use chocolate or composite plate plastic plates, plastic molding, the bathtub product appearance is more complex, with the forming height is deep, the use of common packaging materials materials and machinery are difficult to meet the process requirements, so the appropriate choice of sheet and selection suitable equipment is the foundation of forming excellent sanitary ware. [2]

Plate: plastic board for sanitary ware molding, mainly using pure acrylic (chemical name methyl methacrylate) data or A BS composite materials, and recently developed thermoplastic materials. The special acrylic board used for sanitary ware is excellent in appearance and finish, and its wear resistance is equivalent to aluminum. It is not easy to wipe hair and easy to clean. And if there is an accidental abrasion on the surface, as long as the polishing agent is used, it can be quickly and conveniently repaired and restored.

Mould: in actual production, the design drawings or samples formed by the sanitary ware are designed first, and the molding mold is designed and processed. Plastic molding die is usually made of aluminum alloy or resin mold. Aluminum alloy dies have long service life, good technological characteristics and high surface finish. But due to the high cost and long processing cycle, the application of conventional sanitary products is limited.

Vacuum forming: according to the requirements of sheet cutting good in plastic molding machine for furnace heating and softening acrylic sheet generally at a temperature of 180-220 degrees, 140-190 degrees) composite plate generally softened sheet through the mechanical pressure in the mold, mold sealing conditions, by blowing up the compressed air or the vacuum suction plate, hot stretch the deformation, adsorption on the mold surface, as the time to start the cooling fan, the material harden molding, demoulding, put out products.

Adhesion: after molding, the raw material should be reinforced with resin. The so-called adhesive is usually made of unsaturated polyester resin and glass fiber at the bottom of the sanitary material, so that the molding product has enough strength. In general, there are 2 kinds of coating methods: mechanical spraying and manual application. Mechanical spraying is using a special spray gun to spray the resin and truncated glass fiber to the bottom surface of the sanitary ware, and then press it with robot or manual press roller. Most of the current sanitary ware production is mechanical application. Apply adhesive is completed, the best in the constant temperature curing furnace in 4050 DEG C - drying room is fully cured after deformation isothermal curing products, obviously decreased after.

Cutting edge: apply the stick after the product after curing, began cutting edge cutting, manual cutting and laborious, it is difficult to guarantee quality, and serious security risks.

Punching: the punching on the sanitary ware of the bathtub, if it is on a plane, it should be machined by machine as far as possible, such as porous drill. The device holes such as sprinklers and other sides can be machined by machining centers or mechanical arms (industrial robots), but because of the expensive equipment, most of them are manually operated at present.

Grinding: the device holes on sanitary wares should be grinded for preventing leakage. Special grinding head is used for grinding. A ring type device plane is grinded out of the adhesive layer on the back of the sanitary ware, which is more conducive to leak protection for fittings installation. This technology can not be ignored.

Support: the sanitary brackets are solid wood, plastic, steel structure and other materials, which are made more by the stainless steel square tube. When the adhesive is applied, the cushion or frame of the mounting bracket should be fixed on the right place of the product, then the bracket can be installed by the way of screw or clipping. The quality of the sanitary support will affect the safety of users. Therefore, the stents of the sanitary ware must be made sturdy and stable.

Assembly: water parts and electrical appliances should pay attention to waterproof and ensure safety. So far, a acrylic bathtub has been made.
