Injection molding temperature control system

Injection molding Pet Preform temperature control system is a very important factor in the design of injection mold. The injection mold is used as a heat exchanger to cool the 200°C plastic melt. The final mold shaping temperature control system will directly affect the quality of the injection mold. Workpiece. effectiveness. The temperature requirements of the mold depend on the type of plastic raw material and the quality of the plastic part. If the molding temperature is greater than 80 ° C, the heating system should be set.

The following are the effects of the molding temperature control system on:

The quality of plastic products, including dimensional accuracy, shape accuracy, mechanical properties, surface quality.

Production efficiency is 2/3 of the entire injection cycle, and shortening the cooling time is the key to increasing productivity.

In order to increase the efficiency of the cooling system and the uniform temperature distribution of the cavity surface, the cooling system should be designed as follows:

The cooling system should be placed earlier than the demolding mechanism.

Make sure the center distance of the cooling tube and the distance between the cooling tube and the cavity wall.

Reduce the temperature difference between the influent and the effluent.

Strengthen the cooling efficiency of the gate.

The cooling channel should not be placed on the weld.

Two-Color Pet Preform Mould Making

The difference between over mold and two-color injection mold: over mold refers to first molding a part and then inserting it into another Pet Preform Mould to become a new part.
Two-color includes independent two-color and mixed two-color: Independent two-color refers to two colors made on one machine, usually by moving the cover mold (by flipping the mold). A double mold requires two sets of molds, two sets of the same cavity, and two sets of different covers. The two sets of formwork are interchangeable; mixing two colors requires only one set of molds and a dedicated plastic machine, which is an attachment to two separate nozzles and independently controls the injection parameters of each nozzle.
Mixed two-color injection molding process:
The main injection unit is mounted in the center of the fixed platen. The side injection device is mounted vertically on the mainframe at a certain oblique angle, which makes full use of the space without occupying a large floor space.
The main injection unit and the side injection unit can be separately controlled and produce mixed color products according to different requirements.

Injection Molding Pet Preform Mold Composition

The injection molded Pet Preform mold consists of a dynamic mold and a static mold. The movable mold is fixed on the movable plate of the injection molding machine, and the fixed mold is fixed on the fixing plate of the injection molding machine. During injection molding, the moving and stationary molds close and form a feed system and cavity. When the mold is opened, the movable mold and the static mold are separated for taking out the plastic product.
The mold structure varies depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, but the basic structure is the same. The mold is mainly composed of a feeding system, a temperature regulating system, a molded part and a structural part. Feed systems and molded parts are parts that come into direct contact with plastic and vary with plastics and products. On plastic molds, they are the most complex and varied parts with the highest demands on processing gloss and precision.
The feed system is the portion of the flow path through which the plastic enters the cavity from the nozzle. It includes main runners, cold section plugs, sub runners and sprues. The molded part is an element that forms a shape of the product, such as a movable mold, a fixed mold, a cavity, a core, a molded rod, and a vent.
1. Feeding system
The feed system is also known as the runner system. This is a set of feed channels that direct the plastic melt from the injection molding machine to the mold cavity. It is mainly composed of mainstream roads, auxiliary runners, gates and cold section plugs. It is directly related to the molding quality and production efficiency of plastic products.
Main runner
This is a passage that connects the nozzle of the injection molding machine to the sub-flow path or cavity. The top of the main wheel is concave for easy connection to the nozzle. The inlet diameter of the main flow channel should be slightly larger than the nozzle diameter (0.8 mm) to avoid spillage and to prevent blockage due to inaccurate connections. The diameter of the inlet depends on the size of the product. Usually 4 – 8 mm. The main diameter should be extended inward by a 3 to 5 degree angle to help the sprue margin to be demolded.
B cold section
This is a hole at the end of the main runner that collects the cold material left between the injection molding ends at the end of the nozzle to prevent blockage of the sub-gate or gate. If cold waste is mixed into the cavity, it can cause internal stress in the product. The cold section plug has a diameter of about 8 – 10 mm and a depth of 6 mm. In order to facilitate demolding, the bottom is usually supported by a knockout pin. The top of the knockout pin is preferably designed as a meandering hook or a recess is provided thereon. Then the main runner allowance will be smoothly pulled out when demoulding.

Jilian Mold Production Qualified Pet Preform Samples

Once your China Pet Bottle order is confirmed and the deposit is received, the Gillian mold engineer will provide an analysis report and the customer will receive information including gate location, thimble position and other design details. For complex products or large-size products, especially those that require hot runners, we will use mold flow analysis to simulate potential defects or imperfections by simulating the injection molding process, as shown in the following figure. In this way, the customer will know the condition of the product before the mold is manufactured. Mold making can only begin once the design has been approved.
In the mold manufacturing process, we will use precision machines such as CNC machining, EDM, wire cutting, and especially 2.5-dimensional measurements to inspect electrodes, parts and products. In this way, we will find unexpected errors in advance. In other words, it allows us to provide good quality while saving time and cost.
Our internal injection department will test the mold by injecting samples. The final qualified Pet Preform sample will be sent to the customer for approval.
