Hi, what are you looking for?

Designing any manufacturing product entails generating virtual products that meet all of the product’s requirements, leading the production process to optimize features and ultimately provide an excellent user experience. And there is no difference in charging pile design for EVs.

The primary goal of the charging pile housing design is to ensure a high-quality enclosure for its components in all possible working and environmental conditions so that they can perform for a long time with minimal periodic maintenance. The chin’s charging pile manufacturing industry has entered a period of rapid growth and Advanced technology. Shenzhen Prolean Technology is one of the fined service providers in this sector, which consistently contributes to optimizing the industry standard in the market.

VI How to select the appropriate method

There are two standard methods for designing an EV charging Pile in the manufacturing industry: sheet metal and injection molding.

Both techniques are applicable and can provide suitable housing while reducing emissions and increasing protection for the charging pile components. However, the mechanical and electrical properties are different and may impact functionality. As a result, to design and manufacture the final product, a thorough understanding of these two methods is required.

Sheet metal manufacturing is the process of creating the product from sheet metal through various metalworking processes, including cutting, bending, welding, surface treatment, and others required operations. The housing design for charging Pile through this approach has several steps, fixing the design requirements to surface treatment.

Step 1: Evaluating the design requirements

Fix the design parameters such as dimensions, working temperature, Insulation capacity, strength, durability, mounting, requirements, connector positions, and other essential requirements of charging pile components that need to be enclosed.

After fixing the design Parameters, choose the material that can fulfill your design requirements. For example, aluminum and stainless steel are the most common material for housing of charging Pile.

Step 3: Fix the shape and clearance

To eliminate the pitfalls during manufacturing, fix all shapes needed to create charging pile housing (L-shape, U-shape, folding locations). It will eliminate any potential risk of cracking and failure. Also, fix the clearance for the components, like where you will mount the switches?

Step 4: Fix the sheet metal thickness

As you fix the design parameters of charging pile housing like required strength, working temperature, and machining process in step 1, select the thickness of the sheet metal that can satisfy all of the parameters. You can use the gauge system of sheet metal to find out the appropriate thickness. 

Also, fix the bend radius for all the bending places needed for manufacturing the charging pile housing according to the width of sheet metal while fixing the thickness. While executing the bending operation, the uneven bending radiuses can cause the material to fracture. 

Step 5: Surface finishing solution

Surface finishing operation is essential to save the charging pile housing from corrosion and aesthetic purpose. Analyze the cost-effective approaches such as powder coating and painting. If you had chosen aluminum as the sheet metal, you could also consider the electrochemical plating which will cost higher.

Injection molding, which involves injecting molten plastic material into a mold, is another efficient method of producing hosing for charging piles.

In this technique, the Raw Material (thermoplastic) is chopped into small pieces and then passed through a hot revolving and reciprocating screw, which melts the plastic and injects it into the mold of housing components.

The central and vital step for Designing charging pile housing is the mold design for the injection. The mold has to be designed as per design requirements and parameters such as dimensions and mounting position of components. Moreover, you must ensure that the part comes out of the mold without damage. Endure all of the walls during drafting are at the same angle as the housing components to avoid these problems.

How to select the appropriate method?

If the selection is made based on the installation circumstances, both production methods produce the optimal components and final housing for the EV charging pile. The location is the most crucial consideration in determining which way to choose. Injection molding, for example, may be appropriate if the charging Pile is located indoors in a garage, parking lot, hotel, apartment, or mall. At the same time, Sheet metal could be the best approach for outdoor locations.

Housing from injection molding can perform for a more extended amount of time at a lesser cost without fatigue damage or surface degradation in indoor areas. There is minimum sunlight exposure and minor temperature variation in the indoor location.

The sheet-metal manufacturing method is well suited to outdoor sites such as highways and city centers, where many vehicles are expected to charge. Metal can withstand temperature variation, vibration, and high impact force. If you’re looking for EV charging pile housing, you can contact our engineer for more in-depth information.

Which is the best approach for the manufacturing of Charging pile housing?

It depends upon location. If you are going to install outdoor, Sheet metal is the best, whereas Injection molding is appropriate for indoor installation.

Which one is a cost-effective approach?

Injection molding is cost lesser than sheet-metal manufacturing. Although if you are not going to manufacture in high amounts, injection molding can cost the same as the sheet metal method.
