Plastic Food Thin-Wall Container Injection Molding

When the wall thickness of food container is lees than 1mm, it can be called thin wall. The definition of thin wall is related to the process/ wall thickness ratio, plastic viscosity and heat transfer coefficient. Thin wall food container injection molding machine produces thin wall products through a stable high pressure and high speed injection system. Nowadays, food packing mostly adopts thin wall injection molding process. Thin wall injection molding machine products have attracted much attention because of their advantage such as low weight, small production scale, less material expenditure and short molding cycle.

What are the advantage of Plastic Food Thin-Wall Container Injection Molding?

● Precision

ZOWEITE® Plastic Food Thin-Wall Container Injection Molding adopts high response oil electric servo system cooperates with linear slide rail to project a rigid support structure. Plastic Food Thin-Wall Container Injection Molding is equipped with high performance injection molding machine device developed for all thin wall applications. Screws, check valves and injection valves are specially customized for the production requirements of thin wall containers to ensure an efficient and stable production process. The configuration of servo system makes the production of the machine more efficient and precise.

● Energy conservation

The energy-saving technical design specially developed by ZOWIETE makes the performance of the Plastic Food Thin-Wall Container Injection Molding the best, greatly improves the energy-saving effect of the machine, and is in a leading position in the injection molding machine industry. The energy-saving technology of Plastic Food Thin-Wall Container Injection Molding not only saves costs for customers, but also further protects the environment, which is more suitable for long-term development.

● Cost

Plastic Food Thin-Wall Container Injection Molding adopts a stable high-pressure and high-speed injection system, which makes the injection molding machine more suitable for molding thinner products. Customers can use the same materials and low-cost materials to produce high quality thin wall products, saving production costs.

● Stable performance.

ZOWEITE® optimized the mold locking structure and oil circuit design of the Plastic Food Thin-Wall Container Injection Molding, ensured the high speed and stable operation of the switching mold, made the injection molding machine have a very low failure rate in the production process, ensured the customer’s production quality and efficiency, and reduced the customer’s later maintenance cost of the injection molding machine.

● Efficient

The Plastic Food Thin-Wall Container Injection Molding is equipped with synchronous structure and mold design greatly shorten the molding cycle time. The cycle time of ZOWEITE Plastic Food Thin-Wall Container Injection Molding is about 5-6 seconds. A short molding cycle can enable customers to produce more products in a certain time, improve the machine production and save time.

What should we pay attention to when choosing Plastic Food Thin-Wall Container Injection Molding?

● Mold test: The Plastic Food Thin-Wall Container Injection Molding must be tested before use.

ZOWEITE will test and commission the machine, mold, and auxiliary equipment the whole production line in our factory. We will send the machine to the customer’s country only after we confirm it will be running well and can produce the qualified products. It ensures the quality of the machine and saves the customer’s mold trial and commissioning time.

● Design of mold material, exhaust slot and gate for Plastic Food Thin-Wall Container Injection Molding

There are many factory to be considered for the product mould of thin wall injection molding, such as mould material, mould exhaust, gate, etc. The material of the mold is very important because thin wall injection molding machine is usually filled with high pressure and fast, so the impact of the material of the mold surface will be particularly severe. Therefore, it is usually necessary to use steel with good hardness and heat treatment of the material, which can effectively prevent the wear of the mold.

● Pressure and speed should be controlled during thin wall injection molding machine

The filling time of thin wall injection molding is very short, and many filling times are less than 0.5 seconds. In such a short time, it is impossible to follow the speed curve or cut -off pressure, so a high- resolution microprocessor must be used to control the injection molding machine; In the whole injection molding process of thin wall products, the pressure and speed should be controlled independently at the same time. The method of speed control in the filling stage of conventional injection molding machine and pressure control in the pressure maintaining stage is no longer applicable. Plastic Food Thin-Wall Container Injection Molding usually uses high pressure for rapid filling, but it should be noted that problems such as scorching, gas trapping and color difference may occur in the injection process. It is necessary to control the molding temperature, screw shear speed and other parameters according to the thermal and shear sensitive characteristics of plastic. At the same time, it is necessary to reduce the filling resistance in combination with die exhaust.

Thin wall molding process is an important branch of modern injection molding, which can meet the needs of many aspects, such as products structure, lightweight, molding cycle and cost. The development of Plastic Food Thin-Wall Container Injection Molding has been a development trend. ZOWEITE Plastic Food Thin-Wall Container Injection Molding can not only use commonly used plastic raw material, such as PP, PE, etc, but also use the popular degradable raw materials that can protect the environment(most of the degradable raw materials are composed of degradable materials such as bagasse and amylase). ZOWEITE can provide customers with Turn-key project, including machines, molds, plant design and auxiliary equipment.
