Why Semi-Automatic Blow Molding Machines Remain Popular?
In an era where automation is rapidly advancing, semi-automatic blow molding machines still hold a significant place in the market. Despite the high efficiency of fully automatic machines, semi-automatic blow molding machines are favored by many small and medium-sized businesses, as well as newcomers to the PET bottle industry. This article will explore the key reasons why semi-automatic blow molding machines continue to be highly sought after.
Lower Cost of Semi-Automatic Blow Molding Machines.
Compared to fully automatic machines, semi-automatic blow molding machines are much more affordable, typically costing only 1/3 or 1/4 of the price of a fully automated machine. A complete set, including the mold, air compressor, chiller, and other auxiliary equipment, costs around $9,000 to $10,000. This low investment makes it an attractive option for those new to the PET bottle industry, allowing them to enter the market with reduced financial risk.
Simple Operation of Semi-Automatic Blow Molding Machines.
While fully automatic blow molding machines boast higher production capacity and advanced automation, they require skilled operators with knowledge in mechanics, electrical systems, and control systems. Any minor issue in a fully automatic machine might require professional intervention, which can be time-consuming and costly.
On the other hand, semi-automatic blow molding machines are much simpler to operate. A survey of 10 customers who had never used semi-automatic blow molding machines before revealed that after half a day of training on the machine’s structure and basic troubleshooting, over 90% of them were able to start production independently. This simplicity makes semi-automatic machines an excellent choice for beginners.
Wide Application for Various Plastic Bottles.
Semi-automatic blow molding machines can produce a wide range of PET plastic bottles, such as water bottles, beverage bottles, cosmetic bottles, and wide-mouth bottles. The machine can handle capacities ranging from 50ml to 20,000ml, providing great flexibility in production. Moreover, changing molds is relatively quick and easy, with a single operator able to switch molds in just 20 minutes.
In comparison, a fully automatic blow molding machine requires more time and effort to change molds, especially if the bottle diameters vary. Additional components, such as heating heads and grippers, might need to be replaced, which can take up to half a day, causing delays in production.
Lower Cost of Molds in Semi-Automatic Machines.
The molds used in semi-automatic blow molding machines are simpler in structure, making them more affordable. For example, a 2-cavity mold for a 500ml bottle costs around $450 to $750, while a similar mold for a 6-cavity fully automatic machine can cost between $2,500 and $3,000. This significant difference in cost is especially relevant for businesses that produce a wide variety of bottle types and sizes.
By choosing semi-automatic machines, companies can reduce their overall production costs, especially in terms of mold investment, making it a more financially sustainable option in the long run.
In conclusion, while automation is the trend, semi-automatic blow molding machines remain a popular choice for many businesses due to their affordability, ease of operation, wide application range, and lower mold costs.
