The production capacity of food packaging is accumulated every second.
But a short cycle does not necessarily mean high production capacity. One flash, one weight fluctuation, and one poor connection during picking up may all result in the saved time being consumed again.
The true effective production capacity is not how fast the equipment runs at one time, but rather how stable, qualified, and deliverable the output is in each cycle of long-term production as much as possible.
Facing the lid of the lunch box, yogurt cup, andPETDonghua Machinery offers three different types of preform products, starting from high-speed filling, precision control, and system collaboration, to reduce waiting and fluctuations in production, allowing every second to be more effectively deposited into production capacity.
01.
Do not let filling slow down the cycle
SEc/e runs at the pace of thin-walled mass production
Thin walled packaging products such as fast food boxes and milk tea cups have large order quantities and fast production cycles, and the unit manufacturing cost is highly sensitive to cyclical changes.
The real test of the equipment is not whether a certain the first mock examination can be filled quickly, but whether the cycle can remain stable and whether the product can continue to be qualified after a long high-frequency cycle.
The Donghua SEc/e servo energy-saving thin-walled high-speed special machine adopts a high response single cylinder injection table, direct drive servo melt adhesive motor, and high-speed control system. The highest injection speed of the series can reach 500mm/s, providing equipment foundation for rapid filling of thin-walled products.
At the locking end, a high rigidity, low strain locking structure combined with linear sliding rails and high-speed smooth opening and closing mold design helps to maintain stabilitymoldParallelism reduces the risk of flying edges and uneven thickness.
By synchronously optimizing the melt adhesive and hydraulic circuit, the connection between the melt adhesive, injection, and mold opening and closing actions can be made more compact, reducing ineffective waiting in the cycle.
For thin-walled packaging enterprises, the value of SEc/e is not just to make equipment run fast, but to enable high-speed production to be continuously and stably converted into production capacity.

Don't let fluctuations swallow up production capacity
The D series maintains the stability of high-purity thin-walled food
Yogurt cups require not only a faster production pace, but also higher requirements for the cleanliness of the production environment, uniformity of cup walls, surface quality, consistency in weight, and automation collaboration.
Especially in multi cavity, in mold labeling, and automatic part picking production, any slight fluctuation in equipment may affect the overall production line rhythm.
Donghua D SeriesAll electric injection molding machineThrough more stable and precise motion control, the process fluctuations in the production process are reduced, providing equipment foundation for continuous mass production of high-purity thin-walled food packaging.
The equipment adopts servo motors and precision ball screws to drive key actions, reducing the use of hydraulic oil and related oil pollution risks. The self-locking five point curved elbow locking structure and high-performance linear guide rail provide stable support for multi cavity precision molds.
In the injection process, the D-series high rigidity injection platform can control the deformation of the mechanism within 0.05mm when injecting at the highest pressure; The injection repeatability can reach ± 0.01mm, and the product weight repeatability can reach 1 ‰ level.
For high-purity thin-walled food packaging, reducing one machine adjustment, one pause, and one batch of unstable products means leaving time for truly effective production.

Do not let the system wait
PET-HS connects bottle embryo efficiency in series
The injection molding process for mineral water bottles and beverage bottles produces PET bottle preforms rather than finished bottles.
After the preform is formed, it still needs to undergo embryo retrieval, water cooling, storage, and subsequent bottle blowing. Therefore, the efficiency of preform production cannot only depend on the single molding speed of the injection molding machine, but also on whether the mold, embryo taking, cooling, and subsequent processes can operate in coordination around the same rhythm.
The Donghua PET-HS small high-speed preform injection molding system integrates the PET-H series dedicated energy-saving injection molding machine with a high-speed side water-cooled multi station preform retrieval device, allowing for better coordination between injection molding, preform retrieval, and cooling.
The embryo retrieval device is directly connected to the injection molding machine control system, reducing the waiting time between different processes. The injection molding machine does not stop due to embryo removal, the embryo removal device does not accumulate due to cooling, and subsequent bottle blowing can also obtain a more stable supply of preform.
The system is compatible with 48-96 cavity preform molds. Under the corresponding molds, materials, and working conditions, the fastest production cycle can reach 8-9 seconds, and it can meet the 24-hour continuous production demand.
When equipment, molds, embryo retrieval, and cooling operate at a unified pace, the speed of a single device can truly converge into the production capacity of the entire production line.
The efficiency of food packaging ultimately needs to be reflected in every timely delivery order.
Let every second count towards production capacity.
