Haochen20 years of focus on multimode cavities and small spacing hot runner

A specific planning concept, including manifolds and pressure plates, will become an important part of the mold review.

Hot runner is a disorderly and advantageous mold component. In mold production projects, CAE computer-aided engineering analysis, resin experiments, and planning concepts can all be completed by the hot runner system supplier. At the beginning of a project, if the hot runner supplier is involved in the work, the mold planner can further optimize the final product.

The manifold is used to ensure that the molten channel can be arranged in a useful manner. In an ideal situation, the molten channel is planned in a symmetrical manner, and the active length and number of turns of all downstream channels are common.

In the case of selecting multi cavity molds or asymmetric molds, the melt channel may include artificial lengths and turning points to balance the system appropriately. This concept is helpful for both mold planners and hot runner planners, ensuring excellent manifold planning.

In addition, it is necessary to choose pressing plate skills to ensure that the closing height and key features required by the customer can be planned. Due to the inclusion ofHot runnerThe nozzle and mold planner also need to acknowledge whether the proximity and cooling of the injection inlet can meet the requirements of the hot runner manufacturer.

The main factors for evaluating the hot runner system include:

1. The flow balance and thermal dispersion of the manifold;

2. Channel scale;

3. Strength of manifold materials in high-pressure applications;

4. Note the scale of the import;

5. Close proximity of cooling and injection inlet;

6. Acceptable for abrasive and corrosive resin composition.
