Facts you Need to Know About Vertical Injection Molding Machine

If you are in the manufacturing industry, you might have heard about the vertical injection molding machine, one essential piece of equipment in industrial plastic manufacturing. Vertical injection molding machine is a manufacturing process that is generally used in the fabrication of plastic items ranging from automotive body parts to toys and trinkets. The vertical injection molding machines come with one principal benefit of being capable to produce tons of identical plastic parts.

Facts about vertical injection molding machine


What is MIN-HUI  vertical injection molding?


Injection molding is the most generally used manufacturing process for the fabrication of plastic parts. A big range of products are produced using injection molding, which change greatly in their size, application and complexity. The injection molding processing needs the use of an injection molding machine, plastic raw material, and a mold. The plastic is melted into the injection molding machine and then injected into the mold, where it chills and solidifies into the end part.

Vertical injection molding differ from other machines


High speed vertical molding machine is the whole motor, general injection molding machine is hydraulic injection molding machine, and hydraulic injection molding machine relative speed is very slow. All electric vertical injection molding machines uses servo motor to get close and open mold, demoulding and ejection, raw material injection and storage, etc. The running speed is precise and quick, greatly improving or improving the production atmosphere and production efficiently. But now the servo electric injection molding machine just has a clamping force less than 850 tons.

Advantages


  • Vertical injection molding can be completely automated and thus permits extremely high rates of production.
  • Injection molding permits for the production of very detailed and intricately designed parts. You will need an engineering design company or an in-house department to make credible designs, anyway, once the part is ready for and produced through injection molding, there is extremely little finishing work that needs to be performed. 
  • You can use a big range of materials in injection molding as well as gather different materials to synthesize desirable material properties in your end product. The mixture of more than one injection molded material is called as co-injection molding. Typically there is very small wasting during injection molding as excess material can be simply repurposed for re-use.
  • You can utilize mold inserts to construct new parts. Amazingly enough, technology such s Polyiet from Stratasys is advancing to the point that you will be capable to print mold tooling from a 3D printer for use in a little scale (10-100 parts) injection molding manufacturing work like prototype testing. Tool life will actually depend on the material used in injection molding, and in particular on the part geometry and the barrel temperature of the injection molded stuff. 

What are the alternatives to vertical injection molding?


Several other technologies are accessible for producing outside of injection molding. Most of these do not match for big scale manufacturing but may be helpful for little-scale projects where only a few 100 or 1000 units are needed. Here are a few to consider:

Spin casting


Spin casting uses a centrifugal force and robber mold instead of the steel mold and an injection molding machine to produce parts. Generally, spin casting is done using cured rubber molds that are produced by casting the molten rubber around the real objective. The benefit of spin casting is that a rubber mold can be an order of magnitude cheaper to produce than a steel tool with an inside cavity. If you are only looking for little number of parts, this I likely to be an advantage fit. Conversely, the advantage to steel tooling is that it holds up much excellent than rubber and is designed to be used in injection molding providing the capability to produce 10,000 of parts from the same mold.

What is latest in MIN-HUI  vertical injection molding?


Technology is forever advancing, and the trend is injection molding is keeping pace. It would be hard to discuss about all of the amazing things in production or soon to be incorporated in the globe of injection molding, but here are a few remarkable things we have read about ourselves:

  • Advances incorporating RFID tags into production part
  • Micro-molding (very precise and very little part production)
  • Printed injection mold tool

PIMT in particular is amazing as it would permit for a baseline steel tool to be retrofitted with 3D printed inserts that would be helpful in certain injection molding scenarios. In particular, PIMT would be helpful for prototype injection molding production where only a little number of parts are needed and the material they were made from was not critical.

How do I pick perfect injection molding machine for my product?


  1. Pick the best type of model depends on your plastic raw materials and product. 
  2. Full shot plan the required “injection volume” from the product weight and the number of mold cavities and pick the right “screw diameter”. To calculate the weight of the finished item, you need to consider the number of mold cavities. For example, the weight of a one product is 10g, one shot for two pieces, and the weight of the finished item is 20g. For the sake of stability, the injection volume usually needs to be more than 1.35 times the weight of the end product, that is, the weight of the finished item. 
  3. Lockable the tonnage of “clamping force” is planned by the plastic and the product. When the raw materials are injected into the mold cavity at high force, a mold-supporting force will be produced. So, the clamping unit of the injection molding machine must give sufficient “clamping force” to stop the mold from being opened.
  4. Put it down determine where the “big column inside distance”, “mold stickiness”, and “mold thickness”, and “minimum mold size” of the machine are right from the mold size to make sure that the mold can be placed down.
