MDP – Moule Design Prototype realizes the design of aluminum injection molds for your small and medium series. Established in the Jura, our company MDP is specialized in the design of industrial aluminum molds. Our group also owns a plastic injection company: Plastmold. Thus, we master the design of your good material prototype from A to Z.

Our aluminum injection molds are productive enough to produce in small / medium series. The aluminum mold is also ideal for making a good material prototype in a short time.

Regulatory compliance: White rooms and clean rooms allow you to meet regulatory compliance for the cleanliness of products like medical devices and components.

For manufacturing contamination-sensitive medical, electronic, or aerospace products, maintaining a controlled environment is crucial for ensuring the quality and safety of the products. White rooms and clean rooms are controlled environments that offer unique advantages. Manufacturers must understand their differences to ensure product quality and safety standards are met. This blog post will discuss the importance of white room and clean room injection molding, focusing on Class 7 and 8 clean rooms and how these controlled environments benefit customers by delivering superior quality products.

When products must be protected against contamination and particulates, white rooms and clean rooms are necessary. By choosing an injection molder with white room or clean room molding capabilities, customers can enjoy several significant benefits:

Controlled access: Typically, only those trained and with reason to be in the white room will have access to reduce the risk of contamination.

Positive air pressure: Clean rooms maintain positive air pressure. This means the air pressure is higher inside the clean room than outside, which prevents outside air from entering the controlled environment and minimizes the risk of contamination.

Reduced risk of product recalls or failure: having a medical device recalled or having an electronic product fail in use can be costly and damaging. By minimizing the risk of contamination, white room, and clean room injection molding can reduce the likelihood of product recalls or product failure, saving customers time, money, and potential reputation damage.

High-quality products: The stringent cleanliness standards of white rooms and clean rooms help to ensure that the final products are free from contaminants and that product specifications can be met.

MDP is the specialist in good material prototypes thanks to its expertise in aluminum and steel molds. The MDP TEAM group is your development center for the industrialization of your plastic and metal-plastic parts as well as for the assembly of your finished and semi-finished products. The good material prototype is made from an aluminum mold and in a very short time thanks to our technological excellence. The good material prototype is a prototype with the same qualities as an injected part, but with a short production time and lower investment.

Our know-how is exported year after year outside France. The quality of our aluminum molds is recognized in this rather restricted sector of plastic injection and good material prototype.

At Intertech, we have extensive experience providing precision parts for a number of industries, including the highly regulated medical industry. We have the technology and environment required to deliver high-quality products that meet your requirements and any regulatory requirements. With our white room or class 7 and 8 clean room molding and assembly capabilities, customers can trust their products are manufactured with the utmost care, leading to better outcomes for their end-users and a competitive edge in the marketplace.

White room injection molding is a process where the manufacturing area is designed to minimize contamination by controlling the environment, including temperature, humidity, and airflow. They rely on a robust HVAC system to filter contaminants out of the air. While white rooms don’t require controls as stringent as clean rooms, white rooms provide a controlled atmosphere for manufacturing products that require a higher level of cleanliness than standard manufacturing settings.

The primary difference between white room and clean room injection molding is the level of cleanliness and how that cleanliness is maintained. Clean rooms, particularly Class 7 and 8, adhere to more stringent standards for air quality, particle counts, and contamination control than white rooms. This makes clean room injection molding a more suitable choice for products requiring a higher level of cleanliness and contamination control. Below we cover both in greater detail.

HEPA filtration: High-Efficiency Particulate Air (HEPA) filters pleated mechanical air filters that can theoretically remove 99.97% of airborne particles with a size of 0.3 microns (µm), according to the EPA.

At Intertech Plastics, we are known to reshape the molding industry for medical, industrial, and consumer products and packaging. Our award-winning systems solve today’s problems with tomorrow’s technology.

In order to offer you a fully integrated solution, we have decided to create a large group in France and in Europe: MDP Team. The combination of our know-how in the design of aluminum molds and plastic injection allows us to respond to all your problems. Product launches, test phases, prototyping, small series… Plastmold, our plastic injection plant, allows us to have an unequalled reactivity for the realization of your industrial project.

Do you have a prototype to produce before launching a large-scale industrial production ? The design of an aluminum injection mold is THE quickest solution to set up. MDP makes your aluminum mold in DAMPIERRE. We then entrust the plastic injection to Plasmold, a subsidiary of the group.

Regular cleaning and monitoring: Clean rooms are cleaned and monitored frequently to ensure they meet the established ISO standards.

Employee PPE and Attire: In addition to normally required PPE, employees follow strict gowning procedures before entering the room, including wearing specialized clothing such as coveralls, booties, and head covers, to minimize the introduction of contaminants.

The International Organization for Standardization (ISO) sets the standard for clean rooms, ensuring consistency and reliability across the industry. Class 7 clean rooms permit a maximum of 352,000 particles (0.5 microns or larger) per cubic meter of air and 60 air changes per hour, while Class 8 clean rooms allow up to 3,520,000 particles (0.5 microns or larger) per cubic meter and have 20 air changes per hour. However, adding additional equipment or workers into the room can increase the number of particulates and change the class level, so the manufacturer must maintain the proper cleanliness level.

Employee PPE and Attire: Personnel working in a white room must wear appropriate PPE as in any manufacturing setting. However, to prevent contamination, they must also wear attire, such as lab coats, hair nets, and beard coverings. Often a separate robing area is used so that particles on clothing are not transferred into the manufacturing space.

Regular cleaning: White rooms are cleaned regularly to maintain a clean environment and minimize the risk of contamination.

Clean room injection molding has stricter environmental controls that must adhere to specific airborne particles and contamination standards. Clean rooms are classified according to the number of particles permitted per cubic meter of air. The requirements for cleanroom classification are set by International Organization for Standardization (ISO) in its standard ISO 14644-1 Cleanrooms and Associated Controlled Environments. The lower the class number, the fewer particles and a cleaner environment. This post will focus on Class 7 and 8 clean rooms.

Air filtration: White rooms use air filtration systems to remove particulates and maintain a clean environment. While not as comprehensive as the HEPA filters used in clean rooms, these systems still provide significant air purity.
