Things About Injection Molds Your Boss Wants To Know

Injection molds are one of the reasons why mass production has become so popular, and why so many manufacturers rely on custom mold makers to produce the perfect mold. Here are things that you may not know about injection molds.

1. Injection molding can be fully automated and thus permits very high rates of production (you can mass-produce parts very effectively through injection molding processes).
2. Injection molding allows for the production of highly detailed and intricately designed parts. You will need an engineering design firm or an in-house department to make credible designs, however, once the part is ready for and produced via injection molding,Custom mold makers have perfected the process well enough that final products can have fine details and incredibly intricate designs to meet very strict requirements.
3. Custom injection molds are often cheaper and more durable than 3D printed molds because the amount of time required to make a complete part is usually in the cooling process.
4. You can use a variety of materials in injection molding as well as combine different materials to synthesize desirable material properties in your final product. The combination of more than one injection molded material  is known as co-injection molding.
5. Injection mold makers can actually use aluminum in the products. It is not a common material, but can be used alongside the more common plastic injection molds. This addition will help when a higher heat tolerance is required.
6. It is rare that a mold is perfect the first time, even with a production mold. so if you work with a tool maker who gives you an 8 week delivery on the tool, be aware that that does not necessarily mean that your part will be useable in 8 weeks.Experts are required to ensure that the final product meets your needs. They can test and measure the mold and first round of injections to see if there is a problem and determine the best way to fix it.
7. Mold inserts can be used to make new parts so that you do not have to recreate a similar insert for different projects. It is a matter of changing the internal cavity instead of redesigning and machining the mold.

Jingwei industry has served the injection molding industry for over 15 years and has a team dedicated to providing you with the most cost effective solutions for design and manufacturing your new products.To know more,Please visit us at :jweimolding.com or via info@jweimolding.com.

Advantages and Disadvantages of Hot Runner Mold

A hot runner system is an assembly of heated components used in plastic injection molds that inject molten plastic into the cavities of the mold. The runner is hot to maitain the plastic material molten. The molten plastic is injected into the hot runner and flow from the heated manifold into the cavity through the heated nozzles. Here we list some advantages and disadvantages of hot runner mould compare with cold runner system.

Advantages

Shorter cycle time

The plastic flows faster than the cold runner, and it has no need to wait the cooling of the runner section. The part can be ejected when solidified. The part with thin wall thickness can have the circle time less than five seconds.

Saving cost

In cold runner mould, the solidified runner section is ejected out together with the part. It wastes the raw plastic material. Hot runner system can help to save the cost of this section. If the plastic is expensive, the economic effect is not small.

Higher quality

The heat can be controlled uniformly in the runner, molten plastic flow into the cavity symmetrically. The finished part has better comestic finish, less sink marks and less warpage.

Advanced technology

Many advanced technologies are developed based on hot runner system, like the PET pre-formed precess, multi-color shot, multi-material shot and stack mould.

Other benefits of hot runners:

• hot runners available for both single cavity and multi cavity moulds
• can be used with most plastic materials and part designs
• are easy to maintain
• reduce the number of moving plates in a mold
• gives good gate vestige
• can use with close pitch mold designs

Disadvantages

Higher tooling cost

The components of hot runner are much more expensive than cold runner. It may be not economic when quantity is not large.

Difficult maching processes

Hot runner system require high accuracy of tooling components. Most of the tooling parts have to be machines precisionly.

Complicated operation and repairment

Compare with the cold runner mould, hot runner is hard to operate and repaire. It is easy for the new users to break the mould due to the incorrect operation.
