The key first step in the production of perfect glass bottles by Shanghai Zunchuang Technology - mold opening and proofing

1. The cost of glass bottle molds

If it's a regular mold, it's about $500 per payment. If it's a glass bottle that requires a good appearance and a strict dimensional deviation, it's recommended to use a spray welded mold. The price is nearly doubled. Therefore, from the perspective of proofing, some manufacturers may have received thousands of molds, but if the proofing fails several times, they will lose money. The main reason is that the cost of wasted production time is too high. In fact, the mold cost is not required by the manufacturer, but collected by the mold factory.

Especially for special-shaped bottles, many products require many improvements to produce qualified samples. Or the process used is different, and the equipment is also different. Different equipment may be difficult to make the same product.

Many domestic glass wine bottles and wine bottles are produced with imported equipment. If there is a need to find professional manufacturers in this regard, then the price. With the improvement of China's economic level, our labor costs have increased significantly, which is still acceptable compared to developed countries, but is high for underdeveloped countries. Especially in recent years, labor costs have increased, and coal and natural gas have increased. Transportation costs have risen, and the unit price of products has increased significantly. (May be 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. Products with good quality must have high prices, while products with low prices have equal quality.

2. Material quality

If the bottle requires good material quality, and the requirement is to meet the pharmaceutical glass material quality, it is best to produce it in a qualified glass factory, so that at least the physical and chemical properties meet the requirements. For molded bottles now, most are small capacity injection bottles and large capacity infusion bottles. Brown bottles are mainly syrup oral liquid bottles.

If you require a good appearance, a good transparency and a good finish of the bottle, you can choose high white materials or some called crystal white materials, mainly high-end wine bottles, such as Wuliangye and Jinjiu bottles. There are also bottles in the daily chemical series, but such products have poorer physical and chemical properties than medicinal materials, some of which may rupture at high temperatures, and some indicators exceed the specifications.

3. Production and price of glass bottles

For glass bottles with a capacity of more than 250-300ml, it is recommended to use a drip machine for production. Most domestic bottles have 6 or 8 orders.

If the capacity is below 250-50 milliliters, it is recommended to use a double drop machine for production. Most domestic products are 6 pairs or 8 pairs.

If the volume is below 50-5ml, there are currently 3 drops and 4 drops in China. 5 drops or 6 drops of equipment, which requires a large quantity

4. Glass bottle proofing time:

In the current market economy, various glass bottle factories are competing with each other and all want to obtain more orders in order to achieve better profits. As a salesperson, you must want to receive more orders. Some glass bottle manufacturers that have been doing well for a long time have a detailed review process for orders, but the review time may be longer. Generally, small enterprises are very flexible and feel able to do so after receiving samples, "Samples can be produced within 20 days. We can calculate that from sample production, we usually find professional mold manufacturers to make molds, and some of them are processed by ourselves. From bottle drawing drawings (2-3 days) to customer confirmation (1-2 days) to mold production, if it is a single drop of 6 groups or a double group of 4 groups, it will take at least 10 sets of molds, and mold production will take about 10 days, (if it is a sample mold, it will be faster) plus other time of 5 days,", This can take up to 20 days, followed by an estimated 5 days for machine proofing, which can take up to a month. However, many customization parties now require samples to be obtained within 15 or 20 days, which means that the manufacturer has to rush in some aspects, and some even sample in mismatched production lines. Products with less stringent quality requirements can also be used. If the product is of a different type, it is difficult to produce qualified samples if the material properties and mold design do not match.
