2K Injection molding

An innovative method of producing molded parts from 2 totally different materials known as 2K molding, double injection molding, or 2 shot, molding.

In this type of moulding two materials with varying properties, colors and hardness are molded together in one composite end product. This process is cost effective. Material selection is key factor for 2k molding. It is used for large scale production.

In 2k injection molding it is possible to perform more operations on the polymer while it is flexible and hot. And different materials can be used to formulate a high quality end product.


In this method one or more injection are used separately to inject plastic into mold. The material is separated […]

What is Burn marks troubleshooting

Burning marks, or dieseling defects, This defect will often show up as black, gray, or brown discoloration on the part surface. This is the result of gasses and volatiles getting trapped, compressed, and heated in the mold during injection. This gas will burn the front of the polymer flow front by the high injection pressures and speed. Burning marks normally occur at the end of fill, or the flow ends, such as the end of the ribs or deep ribs area., we call gas traps, venting defects as well.

What is gate blush?

Gate blush is a molding defects commonly caused at the gate location of molded part, It shows as rings or ripples in the mold cavity surrounding the gate area. This defect occurs when plastics material flow across the mold cavity rather than forming a fountain flow and freezing to the mold cavity. As more material enters the mold cavity, it erodes the material off of the mold surface, causing the blushed appearance, gate blush sometimes we call gate shear defects.

Why need design ribs on the injection molded parts

Injection molding technology is the most common manufacturing technology for producing high volume of plastics parts in the world. The purpose of these parts can range from a picture frame that is never touched to a gear that is used in a moving assembly every day. Many times, the stiffness of a part must increase due to the load applied to the plastic part design. When designing strength into an injection molded part, considerations must be made to accommodate for the manufacturing process. This is where ribs and supports come into the design.

Ribs are thin wall protrusions that extend perpendicularly from a wall or plane. supports are […]

Are you looking for different material on a plastic part surface finish? Plastic parts not only benefit from designs that are pleasing to the eye, but they also benefit from the way a product feels when handled. Depending on the application, you may want your plastic mold part to be as smooth as glass or possess a rough feel to indicate strength and durability. One way to injection mold a molded part with a unique look with different grain on the part surface, which we call mold texture surface finish.

Mold Gate Location

By |2021-09-19T13:22:30+08:00September 18th, 2021|Categories: China mold|Tags: , , |Comments Off on Mold Gate Location

Mold Gate Location Optimization Analysis Theory

The injection molding process is heavily affected by where the mold gate location(s) are placed on the mold cavity.  If the right gate location(s) are not selected the part will have quality issues during the mold trial process.

Wrong gate location will cause Problems including but are not limited to the following:

  • Incomplete cavity fill (short sot)
  • High shear rates
  • High shear stresses
  • High molded in stress
  • Difficult to vent air traps
