Manual sink is not simple, teach you how to judge the advantages and disadvantages of manual sink

Manual sink, as the name suggests, is the whole manual production of the sink, without the use of CNC full mechanization of the production process. This is not the production equipment is not developed, but the characteristics of manual water tank, can only use manual production, the production process has welding, grinding, sand belt, pad paste, spraying, push sand.
 
Now is the age of high-tech numerical control, why still make the sink by hand? In fact, the main reason is that a lot of consumers now like high weight, high thickness of the sink, and only manual sink can meet this demand.
 
Handmade water tank adopts 304 stainless steel, environmental protection and lead-free, water tank thickness is large, weight is large, impact resistance and collision ability is strong, acid and alkali corrosion resistance.
 
Handmade water tank - water tank production process
1, welding
Major is computer combined welding and manual welding, before welding, must first be folded in half after bending cracks manually docking, then computer welding, double groove by two welded single groove welded again, computers need quality full inspection after welding, to ensure the quality of each water tank, the oxidation of good welding with a white line is the best, It is also the unique identity symbol of high quality manual trough. The core of manual groove is that the product does not go through tensile molding, which requires a large amount of manual welding, side seam welding, buckle spot welding and R Angle spot welding. Each welding requires the rich experience and careful operation of the welder to ensure the quality of welding. After the welding is done, it needs to be polished.
 
2, grinding
The polishing of the pure handmade sink is mainly to deal with the welding marks produced by spot welding and side welding, which is the process of re-beautification, so that it can reproduce the flat surface and straight drawing lines.
 
3. Crossing the sand belt
The sanding belt is to deal with the oxidation and welds produced on the surface of the middle of the tank when the computer welds the double groove. The straight line grinding of the welds by the sanding belt can make the welds disappear and reproduce beautiful straight drawing lines.
 
4, stick mat
Stick mat is in the bottom of sink and side wall affixed with environmental protection sponge mat.
 
5, spraying
The spraying material used for pure manual trough spraying is different from that of the stretching trough, and the spraying process is also different from that of the stretching trough. The thickness of the spraying is thinner, the flatness is better, and the natural air can be dried. The common point is the use of environmental protection, formaldehyde - free odor - free water-based spraying materials.
 
6, push the sand
Each manual tank needs to be pushed sand, push sand is the surface of the tank again optimized, push sand is to ensure that each pure manual tank before packaging has a smooth surface, as well as clear straight drawing lines.
 
 
Two, the manual sink - how to judge the advantages and disadvantages of the manual sink
 
1, welding tight, no virtual welding. Welding quality is one of the most important factors affecting the life of the flume. Good welding can prevent unborn embroidery and unsoldering. That's in terms of double slots.
 
2, the general sink needs to have overflow device, the surface looks delicate texture, a good sink will have more exquisite patterns as the overflow hole design.
 
3, environmental health, easy to clean, good flatness. Decide quality and class the most intuitionistic standard is: the burnish after birdbath is cleaned, prevent oil, without stain. Material anti fouling is the first consideration when choosing a sink.
 
4, sewer leakage prevention, accessories precision and precision of the same, with PVC material, and the same service life of the sink, anti-blocking, no seepage leakage.
 
5. The thickness of the general manual sink is 1.0~1.5mm, and the quality of 1.2mm is relatively good. Manual sink, as the name suggests, is the whole manual production of the sink, without the use of CNC full mechanization of the production process. This is not the production equipment is not developed, but the characteristics of manual water tank, can only use manual production, the production process has welding, grinding, sand belt, pad paste, spraying, push sand.
