Lean production: Tongda Machinery further promotes the digital construction of hollow blow molding equipment

[ Star Enterprise of Chemical Machinery Equipment Network ] Nowadays , plastic products are widely used in all walks of life, and hollow plastic products have been integrated into all aspects of life
.
For example, various packaging containers such as bottles, packaging barrels, watering cans, fuel tanks, cans, and children's toys are made by hollow blow molding
.
This is one of the commonly used plastic molding methods, and it is also a rapidly developing plastic molding method
.

 

Blow molding is a secondary molding technology that blows a rubber-like parison closed in a mold cavity into a hollow product by means of gas pressure
.
According to the manufacturing method and process characteristics of the parison, it can be divided into extrusion blow molding, injection blow molding and stretch blow molding
.
At present, the plastic varieties used for hollow blow molding include polyethylene, polyvinyl chloride, polypropylene, linear polyester,
etc.
Among them, linear polyester material is a new type of material that has emerged in the field of hollow blow molding in recent years, especially in pressure-resistant plastic food containers
.

 

　　Suzhou Tongda Machinery Co.
, Ltd.
is a manufacturer of plastic hollow molding machinery integrating R&D, production and sales.
The company's products are mainly plastic extrusion hollow products
.
At present, Tongda Machinery has three branch factories, the largest factory area is 34,000 square meters, and the annual sales have jumped to 450 million
.
Tongda Machinery not only provides important production equipment for large-scale high-quality plastic products such as high-strength assault boats for national emergency rescue, but also provides large-scale blow molding for daily chemical packaging, automobile blow-molded parts, chemical plastic barrels and various civil applications.
Product manufacturers provide various specifications of fully automatic blow molding machines and blow molding blow molding units
.

 

　　It is worth mentioning that in the selection of advantageous enterprises in China's plastic machinery industry in 2021 last year, Tongda Machinery was listed in the "2021 China Plastics Machinery Manufacturing Comprehensive Enterprise" with two economic indicators of "main business income" and "net profit" in 2020.
The 25th and 19th of the "Top 30 Enterprises"
.
Among them, Tongda Machinery ranks first in the list of "Top 5 Enterprises in China's Plastic Blow Molding Machine Industry in 2021"
.

 

　　An important reason for the development and growth of Tongda Machinery is the continuous upgrading of technology
.
The company's HS series automatic servo extrusion blow molding machine was successfully developed in 2015.
It is a high-end model integrating high speed and automation
.
HS series models can be equipped with electric blowing needles and full-servo proportional hydraulic control die-moving mechanism to realize functions such as automatic flashing and flashing collection on blow molding equipment, and start the development of extrusion blow molding machines towards high speed and servo energy saving , and gradually realize the unmanned operation mode
.
In 2021, the HS series of Tongda Machinery will be exhibited in many major exhibitions such as Chongqing International Plastics Industry Exhibition and Chengdu Rubber, Plastics and Packaging Exhibition
.

 

　　At present, Tongda's high-efficiency and energy-saving blow molding equipment has obvious market advantages in terms of high efficiency, speed, precision, energy saving, intelligence and low noise, with annual sales of more than 600 sets and sales of 350 million yuan
.
Taking the TDB-250F double-layer model as an example, this model has perfected the precise control technology of radial and axial parison wall thickness, with a daily output of about 600 200L barrels
.
In addition, Tongda has developed a hollow blow molding machine production line fault diagnosis system and an intelligent software and hardware monitoring platform based on the "Internet + big data" technology, which integrates fault diagnosis and monitoring service function units to realize the intelligence of the entire production process
.

 

　　It is understood that in order to continue the research on lean production technology and promote the automation and intelligent upgrading of equipment, the first phase of the 20,000-square-meter intelligent production base in Tongda will be officially opened in January 2022, and the second-phase project of 35,000 square meters is planned to be opened in December 2022.
The total investment reached 250 million yuan
.
After the project is put into production, a 71,000-square-meter assembly and commissioning workshop will be formed, with an annual production capacity of 2,000 units (sets)
.

 

　　A few days ago, the China Plastics Machinery Association proposed that in 2022, it will continue to do a good job in the organizational appraisal of "new technologies and new product achievements" to promote the transformation of scientific and technological achievements in the field of plastics machine equipment manufacturing
.
Since 2014, the association has completed 15 "new technology and new product achievement appraisals" by Tongda Machinery, Jinming Precision Machinery and other units
.
Among them, the "TDB series intelligent composite flow channel hollow molding machine production line" project of Tongda was identified as the overall technical level reached the international advanced level, and the composite flow channel technology took the lead in the world
.

 

　　Based on the requirements of the current "Internet +" environment, the transformation and upgrading of the blow molding machine industry is at the right time
.
Next, Tongda will focus on the research and development of the upgraded version of high-speed and general-purpose key technologies and equipment with a large amount and a wide range.
Efficient digital production lines will be the direction of future development
.
