Cleanroom Injection Molding of Large Parts
At Elimold, we pride ourselves on our advanced manufacturing capabilities, including a stand-alone cleanroom molding cell. Our commitment to precision and quality extends through every aspect of our production process, and our cleanroom molding cell is no exception. This cell can be specifically used to produce healthcare components that require more stringent environmental controls than a standard production floor, but without the requirements of an ISO standard cleanroom. This will allow our partners to manufacture precision parts with the necessary cleanliness and attention to detail without the high costs that typically come with a cleanroom facility.
Our cleanroom molding cells meet cGMP quality standards, ensuring a controlled environment free of contamination. We understand that maintaining a controlled environment is critical to producing components that meet the most demanding specifications. Elimold employees are trained in cleanroom operating procedures, which reduces the risk of contamination. In addition, our personal protective equipment (PPE) requirements for employees working in cleanrooms further reduce the potential for cross contamination. This includes protective clothing such as hoods, gloves, and gowns.
Production Scale Flexibility
Elimold supports all stages of production. With aluminum molds, functional prototypes are available in 7-10 days. Our bridge mold solutions can deliver 500-5,000 parts during final steel mold manufacturing. For mass production, we operate 24/7 with automated quality checks. Our ISO 9001 certified facility can handle parts up to 150 kg with a tolerance of ±0.15 mm. We have separate production lines for medical and industrial parts to prevent contamination. Elimold takes pride in working hand in hand with its customers to improve business processes, skills and technology to continuously provide innovative custom large plastic product solutions at globally competitive prices.

Quality Control for Large Part Injection Molding
At Elimold, quality control begins before production begins. Our team reviews every design for large part injection molding projects to identify potential defects. We use advanced simulation software to predict material flow, cooling patterns, and structural integrity. This helps us prevent defects such as warping or sink marks in large plastic parts. And we maintain strict control over the raw materials used for injection molding. All polymer resins are thoroughly tested for viscosity, melt flow rate, and thermal stability. Our material traceability system tracks each batch from supplier to finished product. This ensures consistency throughout the production process.
After mass production of the product, each molded large part is dimensionally verified using a CMM (coordinate measuring machine). We check critical features against the CAD model with an accuracy of up to ±0.01 mm. For high-stress applications, we perform additional load testing and fatigue analysis. Our quality reports contain detailed measurement and process data to ensure full transparency. Elimold is ISO 9001 certified and has a documented quality program. Our quality team regularly audits production processes and equipment calibration. We provide customers with first article inspection reports and random sampling data.
Typical Lead Time for Injection Molding of Large Parts
Elimold’s lead time for prototypes is 7-15 days and for mass production is 3-5 weeks. Lead time depends on mold complexity, material availability, and order size. We utilize our in-house mold making team and automated production systems to optimize production schedules. Plus, our 24/7 project tracking portal lets you monitor progress in real time. We assign a dedicated engineer to each order, ensuring fast communication. With years of manufacturing experience, we have generally reduced lead times by 18% while maintaining product quality. If you need to manufacture a product with thicker walls and complex geometries, this will increase cooling and quality inspection steps. For example, automotive parts may take 10% longer than standard parts. We reduce delays by pre-testing materials and using multi-cavity molds for large orders.

What is Large Component Injection Molding?
Large component injection molding, also known as high-tonnage injection molding, is the production of large plastic components using injection molding technology. When molding large components, more than just a larger press is needed; the complexity of the item doubles or even quadruples, and the smallest details become more important. Proper mold design is essential, as even the smallest mistakes can exacerbate possible problems such as uneven textures, weld lines, gate white spots, or flow and weld lines. One of the most significant differences between small and large component molding is the cost-quality, which is significantly higher in the latter. The initial lead time for this method will also be a bit longer than small component injection molding, as this type requires a larger steel block that takes longer to mold.
During large component injection molding, plastic resin is forced into the mold cavity using extremely high pressure. Since the mold is composed of two different parts, a certain amount of force must be applied to hold the two halves of the mold together. This force is called the clamping force, and it can be used to easily calculate the required tonnage – a number that grows in direct proportion to the size of the part being produced. Large plastic injection molding technology is used in a variety of industries to produce a range of products from automotive parts to projectors.
Benefits Of Large Part Plastic Injection Molding
Large part injection molding might require the right equipment, skills, and budget, but it has its benefits too. We can help you experience these advantages if you work with us:
High Volume Production
Injection molding of large parts is primarily done to produce large size parts in big batches, which can be done reliably and with shorter cycle times than other plastic manufacturing methods. It’s a necessity when the same part needs to be recreated thousands of times in succession. This is beneficial if you’re in an industry in need of such parts in a specific time period.
Minimal Waste
Compared to other processes, injection molding of large parts creates fewer waste plastic or scraps, so it’s more cost-efficient. Having fewer scraps means that manufacturers don’t have to waste too much plastic resin in the process. The resin used during the manufacturing process can be maximized.
Fast Cycle Time
Many businesses choose large part injection molding, because it is more efficient. The time it takes for the plastic part to be manufactured is short, so more products can be produced in a short amount of time.
Versatility In Design
Large part injection molding is used to create a variety of products — from plastic decking, to large-size electronic casing and enclosures, to plastic chairs and tables, and many large-format items and designs you can think of.
Why is Large Part Injection Molding a Specialty Service?
Large part injection molding requires specialized machines and tools. That is, they are made with what we call large-tonnage injection molding machines, which consume a lot of resources. They take up more space on the factory floor, and each machine is expensive to operate. The capital cost of just one large-tonnage machine is also much higher than any other injection molding machine. The injection molds used in these machines also require special care. They are very heavy and require special lifting equipment to install and remove as needed. Handling the large plastic parts made by these machines also requires considerable space for preparation, packaging, and storage. These considerations limit the number of companies that can provide large part injection molding services.
Industries Served
Large Part Injection Molding is used across a wide range of industries to produce durable, high-precision parts. From automotive components to industrial machinery and consumer products, the process is ideal for manufacturing very large plastic parts with complex designs. Large Part Injection Molding is able to handle high volumes and a variety of materials, providing consistent, high-quality finished products for both functional and aesthetic applications.
