5 Benefits of Working with a Full-Service Injection Molder 

Benefits of working with a full-service plastic injection molder

If you’re looking to produce a new plastic part, you might think you need to find one vendor for each phase of the project. However, choosing a full-service plastic injection molder that can do everything under one roof has many benefits.  

In-House Expertise

A full-service manufacturer has access to specialists that can assist with everything from design to production troubleshooting. These specialists are dedicated to their craft and can provide highly-focused solutions. This means you’ll be working with a team experienced with handling various design and production situations with clients across many industries.

Time Savings

Time management is an important part of every project. Much time can be wasted when you use several different suppliers to bring together your project. When it’s all under one roof, the project moves seamlessly from one step to the next. 

Hiring a full-service plastic injection molder can also help your team allocate enough time to their primary functions. Having everything you’ll need from idea to production and delivery in one place will help you meet deadlines and keep your project on track. 

Consistent Quality

When you have several “irons in the fire,” sometimes it’s hard to communicate exactly what you want to achieve through each stage of the project. A full-service molder can ensure that the design is manufacturable and that the final part is consistently within all visual and functional parameters needed. 

Long-Term Strategic Partnership

Full-service manufacturers provide more than just mass manufacturing capabilities. They strive to gain a better understanding of your products, your company, strategies, and preferences. Where single-service suppliers offer a transactional experience, full-service manufacturers are problem solvers dedicated to helping your project succeed over time. 


Having everything in one place is convenient, eliminates paperwork and recordkeeping requirements. This is especially important if you run into production issues in the future. Your full-service plastic injection molder will be able to easily access your original design files, collaborate with their expert team, and solve the problem quickly without waiting days or weeks for another supplier to send files or consult on design issues.

Why is ISO Certification Important?

ISO Certification

ISO standards promote a commitment to quality, improved processes, safety, and reduced waste.

There’s no denying that quality, efficiency, and consistency are vital in a plastic injection molding project. When quality standards or processes are lacking, material is wasted, product quality diminishes, and costs rise.

Because quality control standards and processes are important for each project, it’s smart to work with a plastic injection molder that is ISO certified. This ensures that the manufacturer has an active quality management system and is striving to continually improve processes.

What is ISO?

ISO is the International Organization for Standardization. It’s currently recognized in 163 countries and has published 22,482 International Standards and related documents for nearly every industry.

ISO standards promote consistency across the board for products, services and systems along with assurance of quality, safety and efficiency.

Companies are not required by law to adhere to ISO standards or to get certified, but  those that do are typically committed to continuous improvement in their businesses.

“ISO International Standards ensure that products and services are safe, reliable and of good quality,” (

There are several different standards in ISO certification, with ISO 9001:2015 being the current most common for any business type. There are additional standards specifically designed for environmental management, medical devices and equipment, gas and oil industry, and others.

How ISO Impacts Manufacturing

ISO certified manufacturers must identify, document, and continually update their processes to ensure quality controls are in place and are being followed consistently. Implementing the ISO standard helps manufacturers consistently cut costs, reduce waste, and improve customer satisfaction with quality products.

The ISO standard is built on the principle of continuous improvement; employees at every level are encouraged to always look for ways to improve. It’s important to get feedback from every stage of the process in order to continue improving.

Adopting ISO standards results in increased customer satisfaction, efficient processes, fewer errors, and reduced overall costs.

The Certification Process

One of the reasons some companies decide not to pursue ISO certification is that it can be a daunting task. Certification requires a rigorous evaluation of the company’s processes. A quality management system is implemented to outline the company’s best practices followed by strenuous internal and external audits of the newly-implemented processes and standards. The certification process – from start to finish – can easily take over a year.

After certification is achieved, there’s still work to do. Internal audits are continually conducted throughout the year and one external audit is conducted per year to ensure the company is staying on track and still effectively implementing the ISO standard.


Selmax Corporation takes pride in meeting ISO 9001:2015 standards and maintaining our certification. We believe in “People – Process – Product”. Every day, the Selmax team is committed to delivering the highest quality products to our customers. We have refined our processes over the past 47+ years to ensure we’re doing all the right things to get the best results.


Things to Consider Before Injection Molding

Injection molding is a great option for manufacturing high-quality plastic parts of different shapes, sizes, and colors. It is efficient and cost-effective, making it the most popular option in most cases. This is especially true when there are high volumes of parts to produce.

Being prepared before you reach out to an injection molder will help to expedite your project timeline. It will also prepare you for cost, time to production, and other components of the project that you may not have considered.

Do you have CAD drawings of the part you’d like to produce?

Plastic injection molders need detailed dimensional drawings that provide information about the size and complexity of the part. 3D CAD model files are the best. The injection molder will evaluate the CAD drawings and advise on the best design for manufacturability.

If you don’t have a CAD model, that’s ok. Typically, injection molders can work with you to develop it. Just plan to spend some time and project budget on developing a good manufacturable design…it will pay off in the long run.

What material is the part to be made from?

In many cases the plastic material is known. In others, it needs to be determined. An injection molder will need to know how the part is going to be used, the type of environment it will be used in, and what wear and tear it will experience over time. When they have these answers, they will be able to recommend options for resins and additives that will give you the best performance and durability for your part within the project budget.

How many parts do you plan to produce?

The injection molder will need to know how many parts you need produced and on what frequency over the life of the project. This will determine the material the injection mold should be constructed from and the number of mold cavities it must have to achieve your required production levels.

Do you need prototype parts to work out potential design issues?

Some parts are simple and straightforward. Others are more complex. Prototyping using 3D printing, for example, is an excellent way to reduce the technical risk for a new injection molding project. It is much easier, and less costly, to discover a design issue and fix it before you’ve made the sizable investment in an injection mold.

What is your budget for the project?

Plan to spend the largest portion of your budget on the injection molds. A large up-front investment is to be expected. It is designed to be recovered over the long-term manufacturing of thousands or millions of parts.

Mold costs will vary from one project to another depending on tolerances, number of cavities, and estimated production life. If you’re projecting to run millions of parts over several years, you will likely opt to spend more on a high quality mold with a high number of cavities. This will translate into lower maintenance costs and lower price-per-part over time.

On the other hand, if you have thousands of parts to run in a relatively short amount of time, you may opt for a lower quality tool with less cavities. The mold costs will be lower, but the part price will be higher. Additionally, if you extend the production life beyond what you originally planned, you can expect high maintenance and repair costs over time.

Next Steps.

If you’re ready to get started, consider working with a turn-key manufacturer. They will be able to handle every step of the process from design to distribution. This allows for better communication, shorter lead times, and a smooth process from start to finish.
