How to Evaluate Custom automobile Injection Molders

-

Automobiles must perform consistently in all aspects, including cooling, heating, fuel delivery, and powertrain. A manufacturer must partner with an injection moulder to achieve these critical functions.

To objectively evaluate potential partners in custom injection molding, you need to ask specific questions. This will help determine their qualifications, specializations, and if they are a good match for your needs.

CERTIFIED?

IAT16949 is the standard for quality management in the automotive industry. This certification shows that a molder is committed to quality and willing to uphold the highest standards in automotive engineering and manufacturing.

A molder must not only be certified but also have a track record of success in the manufacture of automotive parts. Their experience is measured by their ability to understand the factors that affect part performance and quality.

Expert knowledge of certain resins for automotive parts, moldability Tolerances and dimensions

Functionality of finished parts, in particular as it relates working within certain design constraints to deliver sufficient robust components

MANUFACTURABILITY DESIGN STUDIES

Molders who are familiar with the automotive industry know the importance of time. It is essential that components are designed and fit properly. Failure to do so can result in wasted time and money, as well as costly product retooling.

A molding partner who conducts thorough design for manufacturing studies can help you save time and produce quality parts.

Mold flows are used to verify the design and material performance, or reveal areas that need improvement. Mold flow analysis, for example, can help identify incorrect gate locations in part designs. It is important to know about the corrective actions that can be taken without causing significant cost or time loss.

Reviewing design prints can help determine the dimensions and tolerances that an automobile component will need before it is sent to the mold. This eliminates the frustration and time spent on resolving moldability or trapped steel issues. These problems can delay progress by as much as a month, which is a major detriment for any manufacturer.

METAL-TO-PLASTIC CONVERSION

Forward-thinking is the hallmark of a true partner in custom injection molding. They will not only produce parts that you have already made from plastic efficiently, but they will also identify potential opportunities to make metal parts out of plastic to reduce vehicle weight and costs.

This requires that the molder has a deep understanding of metal-to plastic conversion. To ensure uniform wall thickness and consistency of manufacture, for example, if a piston made from die cast metal has pinholes, the new component must have larger holes to allow heavier pins to pass through.

What Is Plastic Mold?   What is plastic mold? The tooling used for plastic injection molding is called plastic mold or plastic injection mold . Most plastic products are molded by plastic molds. Plastic molds are divided into two types: thermosetting and thermoplastic mold ,according to the molding plastic characteristics. Based on the molding process, the plastic mold is divided into plastic injection mold, blow mold, casting mold, pressing mold,and so on. The injection mold is made up of two main sections: the moving half and the fixed half. The moving half is mounted on the moving platen of the injection molding equipment, and the stationary half is mounted on the stationary platen. Over the injection molding, the moving and the stationary half are shut to develop an injection structure and a cavity structure. Once the mold is open, the moving half and the stationary half are split up to clear away the plastic item from the plastic mold. As a way to decrease the mold de

Injection product stress mark solution

On plastic injection products, especially for raw materials such as ABS, PP and PC, you will often see shiny stress marks on the surface of products, such as injector pin stress marks, insert stress marks and stress marks of wall thickness difference . These apparent shiny, white markings are the result of internal stresses , which are nothing more than orientation and cooling shrinkage stresses. The irregular stress marks near the gate are caused by the typical orientation stress, and the difference of wall thickness is the result of orientation and contraction stress, those stress marks are made by ejector pins and sliders . Normally , with the increase of holding pressure and time, the first occurrence is the stress mark of wall thickness difference, the stress mark of ejector pin, then the stress mark of meat thickness difference, and finally the irregular stress mark near the gate (gray section will appear on the side), which of course also depends on the specific structure of the
