HRSflow developed new hot runner solutions to simplify the injection molding process

HRSflow has developed three innovative solutions to optimize injection molding processing and at the same time simplify routine maintenance of hot runner systems: Three Layer Tip, Pressure Block and Thread Safe Kit. Three compact and smart components to achieve great results.

Three Layer Tip and Thread Safe Kit

Three Layer Tip is a special coating-free tip made of three materials, one of which is a copper bushing internal to the flow channel to improve thermal conductivity.

The new design provides increased temperature at the gate thereby improving processing of materials such as glass filled fiber.

Thanks to the use of a special material and the removal of any coating, the new 3 Layer Tip ensures wear reduction of the nozzle tip, elimination of black spots on the molded parts and an optimal mechanical resistance.

Although these improvements have been produced especially for the automotive lighting sector all injection molded parts with high cosmetic requirements can benefit from this new product.

The injection molding process, demands an optimal thermal profile in the hot runner system and has a crucial role for ensuring the quality of the finished part.

A non-uniform temperature is known to cause flow imbalance, warp, and flow marks.

Pressure Block

Pressure Block, is a new component designed by HRSflow made with special low heat conductible materials.

It is positioned between the hot runner system and the mold which increases the clamp plate stiffness under load, and at the same time provides an optimal thermal profile along the whole hot runner system.

The main feature is the flexible positioning without negatively affecting the thermal profile of the hot runner system.

Optimizing the injection molding process is fundamental for production of a quality finished part but simplifying the routine maintenance is equally important.

The new Thread Safe Kit provides both requirements.

A special bushing positioned between nozzle and manifold, provides easy nozzle removal without thread damage when processing materials such as PMMA and PC.

The new design eliminates thread seizing between the duct and manifold allowing for simple removal of the nozzle from the manifold for routine maintenance in any condition.
