Dependable Plastic Parts

and Services

Many people don’t realize plastic injection molded products are part of their everyday lives. From your car and electrical devices to your pool and kitchen appliances, these parts are all around us and span multiple industries.

As such, plastic parts must be of the highest quality and dependability. Modular Molding International, Inc. has the range of services, expertise, and press capacities to meet this need. Our end-to-end capabilities, including design, tooling, production, and inspection, ensure on-time deliveries, streamlined inventory management, and pristine products.

MMI is proud to be a dependable team that delivers the industry’s most reliable, cost-effective plastic injection molding services without sacrificing quality.

Precision and Collaboration for Flawless Results

MMI’s team conducts a comprehensive design review with each client to develop a deep understanding of their needs and identify all part and mold requirements, especially geometrically. This collaborative approach, along with our state-of-the-art technology and attention to detail, ensures we create the highest quality products possible within the customer’s timeline and budget.


We recognize that each client has unique specifications, and our design engineers prioritize incorporating any feedback or adjustments throughout the design process. This open communication ensures that the final product is functional and optimized for manufacturability, lowering production costs without sacrificing performance.

Utilizing industry-leading CAD programs and SOLIDWORKS software, we create highly 
accurate 3D models of your plastic parts, which are the foundation for efficient and precise 
production. SOLIDWORKS allows us to simulate real-world conditions and test part performance virtually, reducing the likelihood of costly mistakes and optimizing cost savings, 
productivity, and time-to-market. In fact, using SOLIDWORKS results in a 25% faster time-to-
market compared to traditional methods.


Using advanced software tools like SOLIDWORKS also helps us identify potential issues early
on, such as design weaknesses or areas where material waste can be minimized. We 
continually refine and perfect the design to maximize part strength and ensure the mold’s 
ease of use during production. This proactive design process helps streamline production, 
reduce lead times, and provide our clients with a solution that best fits their budget, production scale, and functionality needs.

Through precision design and a strong partnership with our clients, MMI delivers products that
align with your vision while ensuring optimal performance.

Global Manufacturing Facilities and Rigorous Quality Control

Proper mold tooling cannot be overemphasized. Like the design phase, tooling is a 
complicated process that requires deep expertise and rigorous quality control standards.


MMI understands that the molds’ precision directly impacts the final product’s quality, so we invest heavily in our tooling process. Whether we’re creating simple single-cavity molds or complex multi-cavity molds, our seasoned toolmakers use the latest precision tooling technologies and follow a stringent quality plan to create molds that meet exact tolerances. Each mold is designed with durability, ensuring long-lasting performance that exceeds clients’ 
specifications.


With our fully owned and operated global manufacturing facilities, MMI can produce high-quality molds at competitive prices while maintaining complete control over the quality and timeline of every project. Our overseas facilities are strategically positioned to provide the best cost savings, all while ensuring the highest standards of craftsmanship.

The key advantage of our global facilities is that we have complete oversight of every step of mold creation. This direct involvement allows us to guarantee that each tool is built to specification and fully optimized for mass production. We don’t just focus on the technical aspects of tool building. We also prioritize cost-effective solutions. By leveraging economies of scale, we can provide high-quality tools at prices that make sense for our clients without compromising on the precision or longevity of the mold.


Our engineers conduct rigorous quality checks throughout the tool-building process to ensure that every mold meets the strictest standards. From material selection to final inspection, we provide the molds built to perform optimally, delivering the highest-quality parts with every cycle. These quality checks also help identify potential issues before production starts, allowing for adjustments that minimize delays and ensure the final product meets the client’s expectations.

Versatile Production
for Every Scale

MMI does it all! With over 30 state-of-the-art injection molding machines, we can handle various project sizes, from low-volume production to high-volume manufacturing. Our machines are equipped to process multiple materials, including thermoplastics, PVC, and Lexans, giving us the flexibility to meet the diverse needs of our clients in industries such as automotive, pool and spa, and consumer goods.

Whether you require just a few hundred parts or millions, MMI has the expertise to deliver consistent quality across all runs. We focus on maintaining fast cycle times for high-volume production, leveraging eDART to reduce waste, and ensuring uniformity across all parts. We optimize each production run to minimize costs while maintaining the integrity and precision of each part.

For smaller runs, we use the same high standards of quality and efficiency to deliver excellent results without the need for large-scale manufacturing. MMI’s ability to offer both low- and high-volume runs ensures that we can accommodate projects of any size with the same attention to detail, reliability, and cost-effectiveness.


Our technicians and engineers closely monitor the production process, fine-tuning machine settings and parameters to ensure that parts are molded within the tightest tolerances. This expertise allows us to produce highly complex parts while maintaining the strength, durability, and functionality our clients require. No matter the scope of your project, MMI is equipped to deliver consistent results that exceed expectations.

ISO-Certified
Quality Assurance

Quality assurance is an integral part of MMI’s philosophy. We believe that each project, whether large or small, requires a balance of the needs and expectations of the customer, the mold, and the final part itself. Our job is to harmonize these factors and deliver a product that satisfies all three, ensuring that the result meets or exceeds our client’s expectations while remaining cost-effective.


We are compliant and certified with ISO 9001:2015. Our ISO-certified inspection processes ensure that our parts meet the highest quality standards. Following rigid quality control procedures, our team rigorously inspects each part for dimensional accuracy, surface finish, and overall functionality. Whether we are manufacturing a single prototype or a high-volume production run, our inspection processes are designed to catch even the slightest defects before they can affect production.

This commitment to quality inspection is found in every project step, from design and tooling to production and delivery. By maintaining these high standards, MMI guarantees that every part that leaves our facility is defect-free and ready for use in your products. We see our inspection services as a safeguard for quality and a way to ensure our clients are delighted with the final product.


Our philosophy is simple: we balance the needs of the part, the mold, and the customer to deliver high-quality, cost-effective solutions. Let us help bring your vision to life with our expert design, tooling, molding, and inspection services. Contact us today to discuss how we can support your next project.
