  Mold plate

  All mold plate parts are processed by 4Cr13 die steel. The surface hardness of the plate is high, more than 32 degrees HRC, which can effectively reduce the corrosion of the mold surface and slight bumps, and ensure the efficiency of the mold.

• 

  The structure of mold parts

  1. The core mold parts are made from S136 high-strength stainless steel imported from Sweden. After processing, the hardness up to HRC52-54 degrees, ensuring the mold lifespan.

  2. The core adopts taper lock design, easy injection molding and air exhausting, ensure no short shot;

  3. The two taper lock design of neckring, precise positioning, more durable,  can withstand high pressure injection;

  4. The water channel of cavity adopts a spiral independent rapid circulation structure, to ensure fast cycle time;

  5.Improved parts process, all tapers and surfaces are machined precisely to ensure longer life of parts.

• 

  Neckring Coating

  The neckring can do the wear-resistant coating treatment. The hardness can reach HRC70°, and it has excellent anti-wear feature, can further improve the life of the mold. The lifespan of the neckring can be extended to 30 million shots.

  Hot Runner

  The hot mold adopts a 2-plate combination type, and the hot runner is directly embedded in the bottom plate milled by the machining center, the hot mold sealing performance and strength are better, and the plate deformation amount is small.

Hot Runner Manifold

Benefits of Huayan Hot Runner Manifold:

1. The hot runner plate is designed in the best natural balance, each design of the hot runner is subject to professional software analysis. results in an optimal thermal balance layout.

2. The cross-sectional size of the runner aperture is determined by different products, We will provide the best injection shear force for different applications to reduce pressure drop and get the best molding cycle.

3. More uniform hot runner plate temperature, temperature difference between melt channels ≤3°C, the consistency of product molding is good.

4.  Has a wider process window and lower AA value and IV drop.

Hot Runner Piston Cylinder

• The valve needle piston cylinder is directly mounted on the heat flow plate to ensure that the valve needle will not bend, be dusty or blackening Glue, there will be no bottlenecks caused by the stylus, or the note is not full.

• The cylinder piston is made of high temperature resistant sealing elements and the maintenance time can be extended to 2 years.

Hot Runner Core Accessories

• The electrical components and core components of the hot runner are imported from Germany or Canada and can be replaced by international famous brands.
• Parts are interchangeable;
• Double-pin plug-in temperature control sensor, maintenance-free design, more accurate detection of hot runner plate temperature.

Hot Runner Sealing Structure

Adopting advanced and unique elastic flow channel sealing technology, the nozzle holder can be close to the surface of the hot runner plate regardless of the state, ensuring that the glue will not leak for a long time;

The back of the cylinder is also elastically sealed, and the cylinder seal is not affected by the cold and heat.

Hot Runner Nozzle

1. The internal structure of the nozzle has been professionally improved, and there is no drift phenomenon during injection molding to ensure balanced injection.

2. The thermal curve of the nozzle is more precise. Under normal production conditions, the temperature of our temperature control components can be precisely controlled.

3. It is within ± 0.5 °C to ensure stable process and product quality.
