Mold Cooling Channel

By |2019-06-10T19:39:44+08:00June 16th, 2019|Categories: blog, Large Plastic Molds, Mold Cooling Channel|Tags: , , |Comments Off on Mold Cooling Channel

Types of Mold Cooling Channels

Cooling channel configurations can be serial or parallel. Both configurations are illustrated in Figure 1 below.

FIGURE 1. Cooling-channel configurations

Parallel cooling channels

Parallel mold cooling channels are drilled straight through from a supply manifold to a collection manifold. Due to the flow characteristics of the parallel design, the flow rate along various cooling channels may be different, depending on the flow resistance of each individual cooling channel. These varying flow rates, in turn, cause the heat transfer efficiency of the cooling channels to vary from one to another. As a result, cooling of the mold may not be uniform with a parallel […]

Mold Parting Line and Gate in Plastic Injection Mold

In Injection Molding (or almost in any type of molding), one of the most basic concepts is Parting line. A Mould is divided into two parts (more for complex designs) so that it comes apart in order to remove the product and reuse it again and again. These two parts are, namely, Core and Cavity. While doing injection molding the cavity needs to be placed inside the core before pouring the molten plastic in. The line where these two parts meet is called the mold parting line. The component produced thus has a single continuous line around its perimeter. This line is usually visible […]

Creating properly parts design and built plastic injection tooling is the most important part of any injection molded parts development. In order to build a successful high-quality plastic injection mold tooling, a comprehensive plan must be followed.

Plastic Injection Tooling Design – If a plastic tooling is designed incorrectly, the penalty may be paid in part quality, injection molding tool repair costs, or longer cycle time (higher component cost) for the entire length of production needs. Because of this we focus on injection tooling design with production in mind and specify parameters up front so that design specification errors or omissions never enter into the quality/cost equation.Plastic Injection Tooling

How to be a successful Plastic Injection Molder

Always I got auction notices in private email inbox, and staring at the photographs of the shops that are going out of business, you were wondering: What does it turn to be a perfect plastic injection molder or plastic injection mold manufacturer?

Many of the auction photographs reveal some of the best state-of-the-art equipment, such as high-speed and precision CNC machine and manufacture tools, the use life of injection molding machines is less than five years old, vision quality systems(projector), CMMs, everything it gets- or so it looks – to make for a successful mold business. Yet, there it all is – listed for auction. So what does it cause? Evidently, it […]

Residual Stress

By |2019-05-31T14:20:21+08:00June 6th, 2019|Categories: blog, China mold supplier, molded plastic parts, Residual Stress|Tags: , , |Comments Off on Residual Stress

A culprit in shrinkage and warpage problems

Residual stress is process-induced stress, frozen in molded plastic parts. It can be either flow-induced or thermal-induced. Residual stresses affect a part similarly to externally applied stresses. If they are strong enough to overcome the structural integrity of the part, the part will warp upon ejection, or later crack, when external service load is applied. Residual stresses are the main cause of part shrinkage and warpage. The process conditions and design elements that reduce shear stress during cavity filling will help to reduce flow-induced residual stress. Likewise, those that promote sufficient packing and uniform mold cooling will reduce thermal-induced residual stress. For fibre-filled materials, those process conditions that […]

Residual stress for molded parts

By |2019-06-04T19:39:41+08:00June 5th, 2019|Categories: blog|Tags: |Comments Off on Residual stress for molded parts

Variable residual stresses arise and the part deforms as layers of different frozen-in specific volume interact with each other

Process-induced vs. in-cavity residual stress

Process-induced residual stress data are much more useful than in-cavity residual stress data for molding simulation. Following are definitions of the two terms, along with an example that illustrates the difference between them.

Process-induced residual stress

After part ejection, the constraints from the mold cavity are released, and the part is free to shrink and deform. After it settles to an equilibrium state, the remaining stress inside the part is called process-induced residual stress, or simply, residual stress. Process-induced residual stress can be flow-induced or thermal-induced, with the latter being the dominant component.

In-cavity residual stress

While the […]
