Plastic Injection Molding Service
One of the greatest inventions in manufacturing is the use of molds to mass-produce items for assembly and sale. If you are looking for an easy way to reproduce the same products while ensuring excellent quality control, molding is a great option.
At MSI Mold, we provide a two-part plastic injection molding service to meet our clients’ varied needs. This includes injection mold tooling and the production of additional parts.
Why Consider Plastic Injection Molds
There are many different ways to structure your production process, so it is only natural that you may be on the fence about this specific option. One of the best benefits of using molds is the scalability. You can use them to create either high or low volumes of the same products for use in commercial and industrial settings.
There is also a wide application when it comes to uses. For instance, companies may rely on our plastic injection molding service to create complex and highly regulated parts for automobile and aerospace use. Meanwhile, some companies use injection molding services to create simple products, such as toys and souvenirs.
The Types of Molds for Plastic Injection To Consider
When it comes to plastic injection molds, you have two primary options to consider. If you’re not familiar with these choices or don’t know which one may better suit your needs, the experts on our team can help you make an informed decision.
Free Standing Molds
As the name implies, we build these molds to operate independently. This all-in-one product of our plastic injection molding service includes the mold base and all other components you may require. When properly designed, they are compatible with any standard, appropriately sized injection molding machine.
This option tends to appeal most to manufacturers who prefer high-quantity production scales and multi-cavity production techniques.
Is this the right option for your business? That may come down to your budget, in terms of time and capital. Free standing molds cost more and take a much longer time to build. Building time may range from three to eight weeks. Even so, multi-cavity parts can save you money on parts, over time.
This option involves the use of a core side insert and cavity side that works well with standard mold bases. It works best for companies planning to manufacture smaller and less complex parts in low quantities. The design may also help companies improve production and lead time.
Despite fewer moving parts, this design is just as robust as the other. This stems from the fact that we are committed to using the same high-quality parts when you choose this plastic injection molding service option.
There are several factors to consider when deciding if this is the better choice for you. The first is the fact that it costs less, which is what makes it a more justifiable expense for low-volume production. If you have a much shorter turnaround time, the five-to-15-day lead time may appeal to you.
The Injection Molding Process
We find that when clients understand the molding process, they are better able to determine what works best for each application. Navigating the cost of our plastic injection molding service also becomes easier. The first thing to note is that there are three main components in the process.
These include raw plastic material, the mold and a machine for injection molding. This is how it all works together.
Step One: Clamping
The plastic injection machine clamps the two halves of the mold together at high force. This is done before injecting any plastic into the mold to ensure an air-tight seal.
Step Two: Injection
The raw plastic material we use is often in the form of small pellets. How much plastic we need depends on client requirements and industry practices. Compliance with safety regulations may also come into play at this step of our plastic injection molding service.
We feed the plastic into the machine and activate compression to heat the plastic. The machine then injects this heated plastic into the clamped mold.
Step Three: Cooling
The temperature begins to fall at the moment of injection. This stems from the plastic materials’ contact with the internal surfaces of the mold, as well as the fact that compression heating is no longer taking place. Once cooled, the plastic re-hardens into its new shape.
While cooling begins immediately, how long it ultimately takes may depend on a number of factors, such as dimensions, thermodynamic properties and compliance. While the plastic cools, the machine prepares more plastic for additional parts created during execution of our plastic injection molding service.
Step Four: Ejection
Once cooled to the desired levels, the machine un-clamps the mold and releases the finished product. The machine then repeats the process with the next portion of heated plastic awaiting molding.
Some Factors Affecting the Cost of Injection Molding Services
We often get asked why this service costs so much. While we cannot speak for our competitors, quality plays a role in our pricing structure.
We prefer to ensure we use high-quality machinery, software and raw material to ensure a mold that meets and exceeds clients’ expectations. While there are ways to cut costs, these measures would undermine our commitment to quality.
Hiring an A-class workforce also plays an instrumental role in our plastic injection molding service offering. These professionals have spent years perfecting their craft and improving their qualifications. In fact, some professionals have invested decades in the field. We pay them accordingly to keep them happy, healthy and focused on the job.
These are the factors that come standard with any project we take on. However, there are some that you may have control over.
We prefer to use high-quality plastics, but some clients may have very specific materials in mind. Plastics for industrial use can range from $1 to $25 per pound, so this can create a drastic difference in the final cost of our plastic injection molding service.
Dimensions and compliance are two factors that may affect how complex the parts are. Undercut features, sharp corners and thin ribs are examples of complex designs. Compliance regulations differ based on industry and can also affect how complex the parts are to satisfy regulations.
Some clients may need more than standard parts. These are some extras that could increase the price:
- Retail packaging
- Secondary machining
- Cell packing
- Layer packing
How We Provide Peace of Mind
Quality control is an ongoing process. It requires a plastic injection molding service that includes long-standing support. We stand behind our products and services and prove this with an unlimited lifetime warranty.
For as long as we keep creating and servicing the tools or parts for your machines, you can count on us to assist with maintenance and rebuilding.
Injection Molding Services
We rely on the use of our state-of-the-art machines to complete molds for plastic injection. However, expensive machines are only half our formula for success. We also invest heavily in our workforce. Once designers finalize the plan, they pass them on to the manufacturing team who create robust solutions for your production facilities and assembly lines.
Finally, our clients enjoy the fact that we maintain full control over our in-house mold building process. This makes it possible for us to advise them directly and answer specific questions that may arise during the process. Handling our plastic injection molding service in-house also means we can keep costs lower.
