- Choose a reliable plastic injection molding company
Injection molding is a manufacturing process that uses a pressurized nozzle to inject molten material into a sturdy metal mold, then quickly removing the finished part and refilling the mold. This method is widely used across various industries, including food and beverage, electronics, automotive, and medical. Due to its compatibility with a wide range of materials, it enables excellent design flexibility. That’s why large part injection molding projects are possible today.
In this blog, we’ll look closely at the essential tips that you must consider for your next large part injection molding project. Read on to learn more.
Make sure to choose the right material
The injection molding process can be used to mold hundreds of different plastic materials. As a result, it’s essential to choose the right material for your large part injection molding project to ensure success. The key is to prioritize a material that will perform well, making it a critical factor in achieving your desired outcome.
When selecting a material for your injection molding project, choose one that is flexible and retains its shape, as well as a material that has a high heat tolerance. Don’t assume that the most advanced plastic material is always the best option, as it may not be suitable for your project and could result in additional costs. Ensure the material you choose meets your requirements and offers the desired qualities.
For example, don’t use glass-filled nylon when the best plastic material to use is polyethylene. The right material for large-part injection molding is the one that best fits the requirements.
Avoid irrelevant design features
For most large-part injection molding projects, having textured surfaces, molded part numbers, or brand logos is not necessary and increases the cost of the process. These added features consume additional polymer resin, making the process more expensive.
However, there are some exceptions, such as aerospace and military applications, that require permanent part numbers. If your project falls under these categories, you can still keep costs down by using mill-friendly fonts like Century Gothic Bold, Verdana, or Arial.
At Richfields, we don’t process fonts deeper than 0.010 or 0.015-inch maximum, as it calls for more resin, which is not economical anymore. We use above 20 pt instead to make them readable still.
Use cosmetics only when required
While adding aesthetically pleasing surface finishes, such as cosmetics, to your molded parts can enhance their appearance, it can also increase the cost. Bead blasting, high mold polish, EDM, and other similar treatments can be expensive and may not be necessary for your plastic parts design.
If the finishes are not a requirement, you can skip them and save money. However, if you still want to add a polished touch, you can do so by polishing just a portion of the molded parts instead of the entire surface.
Consider buying in bulk
The production of small plastic molded parts through injection molding is uncommon, especially in China, as the process necessitates producing hundreds or thousands of prototypes. This makes it more efficient in producing large quantities of parts in a single run.
At Richfields, we can produce hundreds or thousands of large part injection molded parts without compromising the quality, still at an affordable price. That’s why we recommend producing large parts in bulk for our clients. Not only does it saves them from cost, but also reap the benefit of getting each piece at a lower price.
As a result, they can sell their products well in a highly-competitive market.
Choose a reliable plastic injection molding company
Finally, similar to most industries, the plastic injection molding industry has hundreds of small, medium, and large companies. So, for your large-part injection molding project, you should look for a large one that can provide you with the best injection molding process at an affordable cost using its more advanced equipment.
At Richfields, we have a pool of expert injection molders with a great understanding of your product needs, which saves you both time and money until the manufacturing process is successfully done.
Over the years, we have manufactured high-quality and affordable large-part injection molding parts that have never broken our customers’ banks.
Key Takeaway
Injection molding is a manufacturing process popularly known by various industries due to its cost-effective process to produce several parts, even for large-part injection molding projects.
However, it could be costly if you come to other injection molding companies. Here at Richfields, we offer high-quality and affordable plastic injection molding in China! Our expert team can turn your idea into reality with our cost-effective injection molding like no other.
