Glass Vodka Bottle

Glass bottle proofing is a key step in glass bottle production

The quality of glass bottles is closely related to glass bottle design and material quality, production equipment, mold manufacturing and other aspects. Proofing is a very critical step in the production of glass bottles. We usually look at the problem of proofing. First of all, the proofing party must understand the grade of its product, what special requirements such as physical and chemical properties and appearance, and then understand the quality of the product produced by the manufacturer. See if the manufacturer can produce glass bottles with the same quality as the proofing party. This step of proofing directly affects the production cost and quality of the glass bottle, so it should not be ignored.

1. The cost of glass bottle mold

If it is an ordinary mold, it is about 1500-2000 yuan. If it is a glass bottle, the appearance is very good, and the size deviation is very strict. It is recommended to use spray-welded molds. The price is close to double. So from the proofing point of view, some manufacturers may accept After thousands of molds, if the proofing fails several times, they will lose money. Mainly because the cost of wasted production time is too high. In fact, the mold cost is not what the manufacturer wants, but is collected by the mold factory.Especially for special-shaped bottles, many products have undergone many improvements to produce qualified samples. Or the technology used is different, the equipment is different, and it may be difficult to make the same product with different equipment. Many domestic glass wine bottles and wine bottles are produced by imported equipment. If you need to find a professional manufacturer in this regard, and then the price, with the improvement of my country's economic level, our labor costs have increased a lot, compared to developed countries It’s okay, but it’s high for underdeveloped countries, especially in recent years, where labor costs have risen and coal and natural gas have risen. Transportation costs have risen, and the unit price of products has increased a lot. (Maybe due to the support of tax rebates) The domestic price war for conventional products is quite fierce. Therefore, we have a good attitude when making products. The price of good quality products must be higher, and the quality of low-priced products is equivalent.

2. Material quality

If the bottle requires good material quality, and the requirement is to meet the quality of medicinal glass material, it is best to produce it in a qualified glass factory, so that at least the physical and chemical properties meet the requirements. Now in terms of molded bottles: mostly small-capacity injection bottles and large-capacity infusion bottles. The brown bottles are mainly syrup oral liquid bottles. If the appearance is good, the transparency of the bottle is very good, and the finish is good, you can choose high white material or some called crystal white material, mainly high-end wine bottles, like Wuliangye and golden wine bottles. Then there are bottles of the daily chemical series, but the physical and chemical properties of such products are worse than the quality of the medicinal materials, and some will experience high temperature cracking, and some indicators exceed the regulations.

3. The production and price of glass bottles

If it is a glass bottle with a capacity of 250-300 ml or more, it is recommended to use a drip machine to produce, most of which are 6 or 8 orders in China.

If the capacity is less than 250-50ml, it is recommended to use a double-drop machine for production, most of which are 6 pairs or 8 pairs in China.

If the capacity is less than 50-5ml, there are 3 drops and 4 drops in China. There are 5 drops and 6 drops of equipment, this requires a lot of

4. Time for glass bottle proofing

In the market economy, various glass bottle factories are competing with each other, and they all want to get more orders so as to have better profits. If you are a salesman, you definitely want to receive more orders. Some have been doing it for a long time. Some of the better glass bottle manufacturers have a detailed review process for the order, but the review time may be longer. Generally small companies are very flexible. After they get the samples, they feel that they can do it, and they can produce samples within 20 days. We can calculate, from sample production, we usually find professional mold manufacturers to make molds, and some of them are processed by themselves. From bottle drawing (2-3 days), customer confirmation (1-2 days) to making molds. It takes about 10 sets of molds for a single drop of 6 groups or a double group of 4 groups. Mold production takes about 10 days, (if it is a sample mold, it will be faster) plus other time for 5 days, so it takes 20 days at the earliest , And then arrange machine proofing. It is estimated that it will take 5 days, which is close to a month. But now many custom parties require 15 or 20 days to get samples, so the manufacturer has to be in a hurry in some aspects, and some even do not Matching production line proofing, products with less strict quality requirements are okay, if it is a special-shaped product, it is difficult to produce qualified samples if the material properties and mold design do not match.
