The daily routine of a feed bucket
The true test of the hidden injection molding process
In a ranch environment, feed bins are far from simply being able to hold things. It must withstand the continuous heavy pressure of tens of kilograms of feed, withstand repeated handling, stacking, and bumping, and maintain stability for several years under outdoor sun and rain, as well as a huge temperature difference of nearly 60 ℃ between winter and summer.This means that it must simultaneously meet the following hard criteria:
·The barrel structure is stable, and it does not swell, deform, or crack when fully loaded;
·The material has excellent UV resistance and resistance to high and low temperatures, making it suitable for long-term outdoor exposure;
·The lid of the bucket is tightly sealed, effectively preventing rodents, insects, and moisture, ensuring the quality of the feed;
·One time molding as a whole to prevent seam leakage and eliminate potential stress concentration hazards.
These strict requirements ultimately fall on the injection molding process.
Feed barrels belong to large capacity deep cavity products, which require high injection volume, high-pressure filling, and ensure uniform wall thickness and synchronous cooling to prevent deformation and cracking caused by uneven shrinkage in the deep cavity area; When used outdoors, the material should be fully plasticized to reduce internal stress and have good anti-aging performance; The sealing surface of the bucket lid must be flat and free of warping, relying on the stability of the mold locking and the accuracy of the mold opening to achieve tight moisture resistance; The whole piece is formed seamlessly, with high requirements for locking rigidity to prevent leakage.
To conquer simultaneouslyLarge capacity deep cavity, stable weather resistance, integrated sealing, high quality and high yieldThe four major challenges, precise control of the entire process of injection, pressure holding, and cooling, are the core expertise of Zhenxiong servo driven two plate injection molding machines.

Zhenxiong Double Plate Servo Injection Molding Machine
Making the production of large capacity deep cavity barrels no longer a challenge
The Zhenxiong two plate servo injection molding machine series covers a clamping force of 550 tons to 6500 tons, with modular intelligent design that precisely adapts the structural advantages of the two plate machine to the needs of the livestock industry.
▶Large capacity deep cavity bucket
Need to possess:Stable injection of foot and pressure
The setting of injection volume takes into account the material requirements for one-time injection molding of large capacity barrels; Optimizing the dynamic filling performance of thin-walled long channels by adjusting the injection speed to ensure that the melt can smoothly reach the bottom of the mold cavity; Combined with high response servo control, the injection process responds faster and the pressure is more stable. It can hold enough material and complete the long process filling before the melt cools, balancing the requirements of large capacity and deep cavity forming.
▶Long term outdoor use
Need to possess:Efficient plasticizing device
PPThe dedicated plasticizing screw balances plasticizing efficiency and mixing uniformity, which helps to fully disperse functional materials such as UV resistance and oxidation resistance, and more stably exert material properties,
Provide a molding foundation for the weather resistance required for long-term outdoor use.
▶One time molding of sealing surface
Need to possess:More stable mold opening and more precise mold locking
Adopting the fourth generation servo drive system, the repeatability accuracy of the mold opening position is improved by 60%; Combined with precise hydraulic technology, closed-loop control of position, speed, and pressure is implemented to reduce pressure overshoot and switching fluctuations. The balanced locking cylinder is used to achieve symmetrical force distribution, providing more stable control of mold opening and locking, which helps to maintain stability
moldStable adhesion of the parting surface,
Reduce molding fluctuations such as burrs and provide assurance for the stable molding of the lid cover. ▶mass production
Need to possess:Intelligent control+data networking
15 inch large screen
ControllerOne click access to intelligent mold opening, intelligent synchronous temperature control, digital calibration and automatic matching of optimal parameters; High response servo drive combined with temperature PID control, supporting Industry 4.0 networking for real-time data collection of each model, helping breeding equipment factories achieve higher density production.
Zhenxiong not only provides a good machine, but also offers customers a full chain solution from materials, processes to mass production.
