Toothbrush is a kind of cleaning tool in our daily life and it is in direct contact with the mouth. Its cleanliness and safety must meet certain standards. The doctor recommends that the toothbrush should be replaced every three months, so the normal toothbrush at least has three-month lifetime. But what will the toothbrush look like in these three months? Will there be any unexpected surprises?
There are frequent problems in the following three areas, which are also the key points of toothbrush defect check:
Toothbrush defect check found that the use of the product has been significantly affected, but what is the direct relationship between them? The first is that after a single package opening, the product taints easily and the consumer will return or discard the product directly. If a product has a higher return rate, then both the manufacturer and the importer have a large loss. In the article of Why Return, explains the various reasons for return and how the CLI inspection company helps customers reduce return rates and increase operating margins. Secondly, the bristles and handles are the main components of the toothbrush,any one of them will cause a problem in the use of the toothbrush. For example, bristles falling and uneven density can cause a great reduction in the comfort of brushing,which made teeth not clean and the product life is shortened.If the bristles are uneven,the bristles are too hard and too sharp, it will cause gums injury.The soft bristles, the teeth will not be cleaned.The edges of the handle or brush head have sharp edges, the consumer’s mouth and hands may be stabbed or scratched.After the handle is deformed and bent, the use is limited and the force point is different from the original design. These are the various conditions found during toothbrush defect check that manufacturers must keep in mind and avoid.
In order to improve the value of the product, you must solve common defects, starting with toothbrush defect check and trace back to the root cause of the defect.
The bristles are generally nylon filaments and natural bristle. The natural bristles have better clearing effect and the ability to adsorb toothpaste than nylon filaments, but it also has the disadvantage that it is easier to absorb water and dry slowly, so it is relatively easy to breed bacteria. . Nylon filament is soft and soft, can clean the gap of teeth, and has better elasticity, better massage effect, and its wear-resistant and non-absorbent properties, so it has become the material of choice for bristles. When the lower-end bristle material is selected, the bristles are not easy to be colored. In the subsequent planting process, the implanted bristles are easily dropped, the hair bundles are sparse, or the density of the hairs is uneven. And in the next grinding process, the tip of the bristles is difficult to round and sharp, which can easily lead to bleeding gums of consumers.
The handle of the toothbrush is preferably long and straight. The middle section of the handle is slightly curved upwards,which has a certain elasticity and a fixed fulcrum. It is best to form an arc. It is best to choose a toothbrush with a non-slip grip. The main material of most handles is polystyrene plastic particles. If the low-end material is selected, the possibility of odor is great. When the injection molding equipment is not adjusted, the temperature and time of injection are not enough, the handle is easily bent and deformed.Therefore, in the toothbrush defect check, it can clearly see whether the shape of the handle is same with the customer’s signature. In addition, in the middle of the production, the product can be inspected in time. If the importer does not trust the quality inspection done by the factory, the third-party inspection company can be arranged to carry out the during production inspection. For details, please see During Production Inspection.
The packaging materials of large goods are generally corrugated boxes. The number of layers of the carton and the hardness meets the requirements.When the boxes are packed, the protective measures such as foam plates are placed inside, which can protect the products more comprehensively. Of course, the hardness of the individual packaging of the product should also meet the requirements. Otherwise, when the warehouse is carrying goods, or when entering the store, the individual packaging will still be damaged, such as deformation, packaging opening and etc. Most of times due to the wet weather, when the toothbrush defect check, the inspector found that the large number of cartons were damaged. At this time, the factory should be reminded to replace the new carton, otherwise the products are likely to be scrapped.
From every step of the production of the toothbrush to the inspection and packaging, there will be problems in each procedure. If the problem can be predicted and prevented in advance, the complaints of consumers may be reduced. Prevention can be reflected in the selection of product materials and production processes, commission all machinery and equipment,control the temperature and time.In the production of toothbrushes, common equipment include injection molding machines, hair-planting machines, hair cutting machines, trimming machines or sanding machines. The selection of each equipment is also very important. If the factory uses low-end equipment,the production efficiency will be reduced and the product precision is also decreased. For example, when planting hair, it needs one step in place to completely implant the bristles into the hole position and the bristles are not easy to fall.The number of roots of each hair bundle is uniform, otherwise it will cause emptiness and unsuitability. Predictive problems, which is after each toothbrush defect check, the materials and equipment can be improved to avoid defects, so the operation and necessity of toothbrush defect check can really work!
It can be seen that such a small item that we use every day, from material selection to craftsmanship, has such many defects. If consumers do not pay any attention, hey may buy some low-end products!
