When designing plastic enclosures, several factors need to be considered:
Plastic Material Type
A variety of plastic materials can be used for electronic enclosures, with some being used alone while others may be combined. The choice of plastic depends on the specific requirements of the application. For more demanding uses, high-density polyethylene (HDPE) is often selected due to its robustness as a thermoplastic material.


HDPE is valued for its resistance to cold, liquids, and corrosion, as well as its durability, resistance to high temperatures, and cost-effectiveness in production. Other plastics commonly used include acrylic, polyvinyl chloride (PVC), polypropylene, acrylonitrile butadiene styrene (ABS), styrene ethylene butadiene styrene (SEBS), and polyamide (PA).


Here are some commonly used materials for manufacturing plastic electronic enclosures:
Acrylonitrile Butadiene Styrene (ABS):
ABS is effective for manufacturing plastic enclosures, particularly in environments where chemical resistance and impact shielding are required. However, ABS has poor resistance to ultraviolet (UV) light, making it more suitable for indoor enclosures.


Acrylonitrile Styrene Acryl Ester (ASA): ASA is used in applications such as food manufacturing, healthcare, and laboratory facilities due to its antimicrobial properties. It is well-protected against fungi and viruses and can be mounted in areas prone to bacterial growth.


Combination of Polycarbonate and Acrylonitrile Styrene Acryl Ester: Combining different materials can result in superior electronic enclosures. When polycarbonate is combined with ASA, the enclosure gains flame resistance, high-temperature durability, weather and chemical resistance, and impact protection, making it suitable for outdoor environments. However, these combined materials tend to be more expensive.


Carbon Neutral Bioplastic: This new type of biodegradable plastic is suitable for soft case enclosures. Made from naturally occurring materials, carbon neutral bioplastics are certified biodegradable, making them an eco-friendly option.

Design Guidelines And Tips For Plastic Enclosures
 

Today there are many ways to do everything. Similarly, there are some basics to create a good design for plastics as well. You just need to know and apply them in a right direction. Below are the design guidelines and tips for plastic enclosures:

Design: The very first thing that you should keep in mind is the overall quality of the product. Design is the key factor to be focused. It should be different and more appealing as compared to others.
 

Details: You should keep in mind all the details regarding the product. For example a medical product must have different design as compared to the kitchen product. So all the necessary details should be considered.
 

Speed: Time is one of the key factors to be managed as well. It all goes well if you jump in with the right thing and right timing. Continue with your product with normal speed. Neither rush to launch it without proper testing nor take too much time as well.


Phases/processes that should be kept in mind while designing plastic enclosures:

1) Prototype: Once you are finished with the design part, you need to make a sample of the product. This is called the prototype of the product. When you build a prototype, it is then you can test the product for its pluses and minuses. Therefore, you need to design a product that is easy to build and test as well.

 

2) Mold Construction: Being a designer, you should know the complexities, limitations and boundaries of a molding process. This process is preferably used when a whole lot of plastic products are made.

 

3) Manufacture: It is the most cost effective phase. Your design should be easy to produce and easily malleable. Since manufacturing is the most costly process, therefore, your design should be fool proof to meet all the challenges of this phase.

 

4) Assemble and Decorate: Decoration is the phase that needs more attention in your design because in this process product is initially packed and aligned properly.

 

5) Inspection: It is the process that is done to find out all kinds of flaws and shortcomings of the product and to remove if any.

 

6) Packaging and Shipping: Packing and shipping is the phase that needs more attention in your design because seeing is believing. Good design and appealing packing attracts more consumers.

FAQ

Q: How plastic enclosures are made?

A: ABS Plastic Enclosures: ABS enclosures are manufactured using a similar process to polycarbonate, with an emulsified mixture of plastic components heated and injected into a mold. Since it's a thermoplastic material, meaning it can be heated and reformed multiple times, ABS is often recycled.

Q: What material is used for plastic housing?

A: Polycarbonate and Acrylonitrile Butadiene Styrene are some of the most commonly used plastics for electronic enclosures. A PC+ABS thermoplastic blend combines the positive qualities of both PC and ABS.

Q: What is the manufacturing process of plastic housing?

A: Plastic extrusion: Small plastic pellets are melted and extruded through a heated chamber by a screw. Molding: The molten plastic is injected into the mold. Cooling and release: The part cools in the mold until it is solid enough to be ejected, either mechanically or by compressed air.

Q: What is the best plastic for enclosures?

A: ABS is a two-phase polymer blend that provides good all-round performance for electronic enclosures. For that reason, ABS is used in most cases in the OKW range. It is best suited for use in enclosed rooms but is less suitable for outdoor use.

Q: What is the plastic enclosure type?

A: There are many different types of plastic enclosures. Some common examples include:
NEMA
IP
UL 50
PCB
DIN rail
Instrument

Q: What are the compression requirements?

A: Rubber gaskets for plastic enclosures fill the gaps between doors and door frames. Gasket compression promotes sealing, but over-compression can contribute to seal failure. That’s because rubber gaskets are resilient, but only to a point. If an enclosure gasket is over-compressed, the rubber won’t rebound when the compressive stress, such as from a closed door, is removed. This creates gaps and permits leaks between the rubber gasket and the surface of the plastic enclosure.

Q: What is the best gasket material to select for a plastic enclosure?

A: Choosing the right gasket material for a plastic enclosure generally starts with compound selection. For example, EPDM rubber is a cost-effective choice for enclosure gaskets that need to withstand water, weather, and sunlight. Silicone rubber withstands these same conditions along with higher temperatures. However, silicone is more expensive than EPDM and is subject to supply chain constraints that have affected its availability.

Q: What is a plastic enclosure?

A: A plastic enclosure is a housing constructed from polymeric materials such as ABS, polycarbonate, or PVC, designed to protect electronic and electrical components from environmental threats, mechanical impacts, and interference.

Q: What is the best plastic for enclosures?

A: ABS is a two-phase polymer blend that provides good all-round performance for electronic enclosures. For that reason, ABS is used in most cases in the OKW range. It is best suited for use in enclosed rooms but is less suitable for outdoor use.

Q: What material is used for plastic housing?

A: Polycarbonate and Acrylonitrile Butadiene Styrene are some of the most commonly used plastics for electronic enclosures. A PC+ABS thermoplastic blend combines the positive qualities of both PC and ABS.

Q: What are the environmental conditions?

A: Rubber gaskets for plastic enclosures must also withstand specific environmental conditions. For example, if you’re designing a rubber seal for a NEMA 4X fire-rated enclosure, you’ll need a gasket that can meet the rating’s fire testing requirements. If you’re designing a gasket for an IP 65 weatherproof enclosure, you’ll need a gasket that withstands condensation and water spray. Depending on the environment, protection against humidity or chemicals may be what you need instead.
