Plastic mold injection is the best, if not the most efficient method of production of plastic parts on the market. If your business relies on making quality parts in high volumes and record times then you should not look any further. Reliability and user-friendliness are probably the biggest selling points of plastic mold injection. I wanted to have a closer look at what this method brings to the table regarding my needs so I talked to Wunder Mold who showcase why choose this over other options.
High Detail
The molds are able to add a lot of pressure to the plastic enabling detailed and complex designs to come to fruition. It is too expensive and time-consuming to add the details after the basic production is complete. Plastic mold injection saves you time and money by adding detail and complexity on the spot.
Efficiency
One of the major benefits of this method is the ability to produce a lot of plastic parts in very short time intervals. The moment the molds are ready to go, you can expect the cycles to last between up to 2 minutes depending on the complexity, but simpler parts come out much faster. Not only time is saved, but also the material that’s left can be reused, making the whole process cheaper. The amount of scrap left behind is not big, moreover, you save both money and the environment by being able to recycle leftovers. The environment is prioritized and very little waste is generated when the process is over. Reusability makes the production clean and cost-efficient.
Durability vs Flexibility
With the use of filters, you can create plastic parts with different features. Whether you want the parts to be more elastic, or you prefer strength, you can adjust the density of the material which can add more durability in case you need certain parts to be thicker and more resilient. You don’t need to look for different methods or create new projects. Additionally, you can mix different types of plastic at the same time and expand the possibilities. Co-injection molding allows you to add even more detail to your production, and also further specifies the features of each and every part.
Low Production Costs
Plastic injection molding is automated. Machines handle almost the entirety of the process. This means that you need one person to be there from start to finish. Lower labor cost directly translates to the production price making it more affordable for the customer. Fast and quality production leaves very little room for mistakes adding another layer of safety for your investment.
Maintenance
Every mold has a life expectancy and the number of cycles it can complete before they need to be replaced. In general, one mold should be able to complete between 100 and 1 million cycles, depending on the quality of the mold and the complexity of the projects. Regular maintenance like cleaning is expected. You can use air to clean waterways. Molds need to be lubricated often, and also vents cleaned.
What Comes Out
Another benefit of plastic injection molding is that the product that comes out finished is 99% finished. There’s usually no need for any finishing touch unless you need something that can only be done manually.
The downside is that the process is considered expensive if you produce a small number of parts because the whole setup is complex. There are also some boundaries in terms of design; sharp edges and undercuts should be avoided. Plastic mold injection can produce a big number of parts of high quality very fast with regards to the environment and low production costs.
