1、成型：浴缸、淋浴房底盘、背板等洁具成型通常用克力或复合板类塑料板吸塑成型，由于浴缸等产品外观比较复杂，具有较深的成型高度，用普通包装材料所使用的资料和机械均很难满足工艺要求，所以选用合适的板材和选用合适的设备是洁具成型优良的基础。

2、板材：洁具成型用的塑料板主要使用纯亚克力（化学名称甲基丙烯酸甲酯）资料或A BS复合资料，以及近来新开发的热塑性材料。用于洁具的专用亚克力板由于具有优异的外表光洁度，其耐磨性相当于铝，不易擦毛，易于保洁，而且如果发生外表意外擦伤，只要使用抛光剂，即可迅速方便地修整复原。

3、模具：实际生产中先按洁具成型的设计图纸或实样，设计加工吸塑成型模具。吸塑成型模具一般采用铝合金或树脂模，铝合金模具寿命长，工艺特性好，外表光洁度高，但由于造价较高，加工周期较长，惯例洁具产品的生产中的应用受到一定限制。

4、真空成型：把按要求裁切好的板材在吸塑成型机的炉内加热软化亚克力板材一般温度在180-220度，复合板一般140-190度）软化后的板材通过机械压紧在模具上，模内密封的条件下，通过压缩空气或真空的吹涨抽吸，板材热拉伸变形，吸附在模具壁上，视时机启动冷却风机，使板材变硬成型，然后脱模，把产品取出。

5、敷粘：成型后的胚料，要进行树脂敷粘加强，所谓敷粘一般是用不饱和树脂和玻璃纤维复合在洁具胚料的底部，使成型产品有足够的强度。敷粘方法一般有机械喷涂和手工敷贴2种。机械喷涂是使用专用喷枪把树脂和截断的玻璃纤维一起喷射至洁具底部表面，然后用机器人或手工压辊压平，目前的洁具生产中大多采用机械敷贴方式比较多。敷粘完成后，最好放入恒温固化炉在4050℃环境中-烘干房充分固化，经过恒温固化的产品日后的变形明显减少。

6、裁边：敷粘后的产品经固化后，开始进行裁边切割，手工切割费工费力，质量很难保证，而且平安隐患严重。

7、打孔：浴缸等洁具上的打孔，如果在一个平面上，应尽量使用机械进行加工，如多孔钻等。喷头等侧面的装置孔，可选用加工中心或机械臂（工业机器人）进行加工，但由于设备较为昂贵，目前大多采用手工操作。

8、修磨：洁具上的装置孔为防止漏水应进行修磨，使用专用的修磨刀头，洁具背面的敷粘层磨出一个环型的装置平面，更利于配件安装的防漏保护，此项工艺不可忽视。

9、支架：洁具支架有实木，塑料，钢结构等材料，其中以不锈钢方管制作较多。敷粘时把安装支架用的垫块或框架固定在产品的合适位置上，再用螺钉或夹扣的方法把支架安装好，洁具支架的好坏，影响到使用者的平安。因此，洁具的支架一定要做得坚固稳定。

10、装配：水件、电器的装置应注意防水，保证平安。

1. Molding: The molding of bathtubs, shower room chassis, back panels and other sanitary wares are usually formed by blister or composite board plastic plates. Because bathtubs and other products have a complex appearance and have a deep molding height, they are used by ordinary packaging materials. The materials and machinery are difficult to meet the process requirements, so the selection of appropriate plates and the selection of appropriate equipment are the basis for excellent sanitary ware molding.

2. Sheets: Plastic sheets for sanitary ware molding mainly use pure acrylic (chemical name methyl methacrylate) materials or A BS composite materials, as well as newly developed thermoplastic materials. The special acrylic sheet used for sanitary ware has excellent surface finish, its wear resistance is equivalent to aluminum, it is not easy to scratch, and it is easy to clean, and if accidental scratches occur on the surface, as long as the polishing agent is used, it can be quickly and easily repaired and restored.

3. Mould: According to the design drawings or actual samples of sanitary ware molding, design and process the blister molding mold in actual production. The blister molding mold generally uses aluminum alloy or resin mold. The aluminum alloy mold has a long life, good process characteristics and high surface finish. However, due to the high cost and long processing cycle, the application in the production of conventional sanitary ware products is subject to certain restrictions.

4. Vacuum forming: heat the cut sheet as required in the furnace of the blister forming machine to soften the acrylic sheet, the general temperature is 180-220 degrees, and the composite sheet is generally 140-190 degrees.) The softened sheet is mechanically compressed. On the mold, under the condition of in-mold sealing, through compressed air or vacuum blowing and suction, the sheet is thermally stretched and deformed and adsorbed on the mold wall. The cooling fan is started according to the time to make the sheet hard and formed, and then demolded. The product is taken out.

5. Adhesive: The molded blank should be strengthened by resin adhesion. The so-called adhesion is generally combined with unsaturated resin and glass fiber on the bottom of the sanitary ware blank to make the molded product have sufficient strength. Generally, there are two kinds of application methods: mechanical spraying and manual application. Mechanical spraying uses a special spray gun to spray the resin and the cut glass fiber onto the bottom surface of the sanitary ware, and then flatten it with a robot or a manual roller. At present, most sanitary ware production uses mechanical application methods. After the application is completed, it is best to put it in a constant temperature curing oven at 4050℃-the drying room is fully cured, and the deformation of the product after constant temperature curing will be significantly reduced in the future.

6. Edge trimming: After the adhesive product is cured, trimming and cutting will begin. Manual cutting is laborious, quality is difficult to guarantee, and safety hazards are serious.

7. Hole drilling: If the holes on the bathtub and other sanitary wares are on a flat surface, they should be processed with machinery as much as possible, such as multi-hole drills. The side device holes such as nozzles can be processed by machining centers or mechanical arms (industrial robots), but because the equipment is relatively expensive, most of them are manually operated at present.

8. Grinding: The device holes on the sanitary ware should be ground to prevent water leakage. Use a special sharpening head. The adhesive layer on the back of the sanitary ware grinds out a ring-shaped device plane, which is more conducive to the leak-proof protection of the fittings. This process cannot be ignored.

9. Bracket: Sanitary ware brackets are made of solid wood, plastic, steel structure and other materials, of which stainless steel square pipes are mostly used. When applying the adhesive, fix the pad or frame of the mounting bracket on the proper position of the product, and then install the bracket with screws or clips. The quality of the sanitary ware bracket affects the safety of the user. Therefore, the bracket of the sanitary ware must be made strong and stable.

10. Assembly: Water fittings and electrical appliances should be waterproof to ensure safety.
