About the plastic hose just know how much you? - - - - True record: today a class total and give us a few weeks, we had known from the plastic hose to the preliminary understanding, also from the moment the real know a plastic hose from production to the real process of a qualified products, we are a plastic hose manufacturer, we have the production of PET plastic hose, PVC, PE plastic hose, plastic hose shampoo plastic hose and so on, all have knowledge of the plastic hose is learn to master, such ability faster, better and more efficient work. Let me share with you about the time the focus of the dies for the plastic hose and raw materials. One positive, product display for the plastic hoses hose body, a positive show must include four elements: brand name, common name, attribute, net content. Be short of one cannot, can form a product. If it is in the domestic sales of the soft tube mark brand name must be Chinese, and must be a registered trademark. Such as: herbal shampoo, dandruff shampoo is the common name of the product. The nature of the attribute, skill inherent things, such as shampoo, conditioner, etc. ; Refers to remove containers, impurity, moisture, the weight of the outside of the component. Second, the net content of net content must be in the hose body positive marking out, more than 1000 ML ( Contain 1000 ML) The wording volume is greater than 6 mm; While the words under 1000 ML than 4 mm. Hose on the volume with the net content of more than 500 ml, tube perfusion amount shall not be less than 3% of the overall capacity, under 500 ml tube perfusion cold error is not greater than 15 ml, is very strict with the net content, small or error are not qualified. So generally below 500 ml net content of perfusion can't net content for the pumping hose body target, to be above the net content of the original and about 25 ml capacity to the hose, the net content of more than 500 ml generally above the content of the original plus the amount of about 30 ml to hose. Also suggests that the relevant provisions of the net content on hose standard 100 ml or more words must be standard 1 'l', rather than the '1000 ml. Three, the product on the back of the note: hose body can't have the words 'qualified' on the back, these four words cannot be fixed by the manufacturers, the QS must also to production license. The hose body seal the word 'ingredients' is not 'ingredients'; Not excessive use of words to describe quality of ingredients, such as 'natural' 'efficient whitening' and so on four and different raw materials use of raw materials and mould production, we usually use steel mould in production process. PE plastic hose mould: can you share a mold production with PP, generally the material we use are all steel, PE and PP used mold can produce PVC raw materials, PVC corrosive. PVC plastic hose mould: USES the stainless steel, aluminum mold, surface polishing, can't play PE mould, can transform, but it can't share, shrinkage is small. Can play PETG raw materials, but the cost will increase, general rarely production. PET plastic hose mold, mold steel, stainless steel and aluminum mold, transparency and needs polishing. Five, form a finished product of three elements: material, color, mould cavity is a second, relative to the cost would be high, we usually is to use two cavity, two out of four, so that we can save cost, but if the production batch less can order cavity.
