If you are looking for a reliable and experienced plastic junction/wire box mold manufacturer, don't miss WYD Mold. 

WYD Mold is committed to producing high-quality, high-precision plastic junction/wire box molds (circular junction box molds, square junction box molds,rectangular junction box molds), and providing cost-effective mold related services. Although there are thousands of excellent mold companies in China, we are definitely the one who hopes to win your trust and establish a long-term cooperative relationship with you the most.

Select high-quality mold steel and perform a series of operations such as detection, cutting, flying knives, and heat treatment. Eliminate problems such as deformation, sand holes, and cracking of steel during later processing.

WYD mould experienced designers can design the appearance of products according to customer requirements and complete mold drawings.Including product weight adjustment, cooling system design, and various other accessories.

Choose freely from three inquiry methods：

1.You can provide junction box photos with dimensions (Length x Width x Height).

2. According to 3D modeling of your junction box for mould quotation.

3.Express junction box samples to us for inquiry.

Before timely delivery. There are several ways for customers to confirm junction box molds, including the following:1. Confirm the expressed sample. 2. Provide sample pictures and videos, mold pictures and trial videos. 3. Testing mould again when customer is here.

After the final step of the junction box mold is completed, we will select the same model of injection molding machine for trial molding based on the model that the customer will use, to ensure that the customer can start production smoothly and normally after receiving the junction box mold.

WYD mould usually use 5-axis machining for junction box molds. Like 5-axis deep hole drilling and 5-axis CNC milling. Greatly improves the precision of mold processing, reduces errors generated in different processing steps, prolongs the lifespan and durability of molds, and creates greater benefits for customers

There are many steel options for making junction box moulds, but the most commonly used ones are steel P20,steel 718,and steel H13. In order to achieve better cooling effects, beryllium copper is usually embedded at the top of the mold core and along the edge of the mold cavity.

If you don't have any special requirements, steel P20 is the best choice for making junction box molds. Firstly, this type of steel is relatively cost-effective. Secondly, With proper maintenance of the mold, even if the P20 hardness is only 28-30 HRC, the production capacity can reach millions of mold cycles, which means it can produce millions of junction box without any problems.

If your production capacity demand is huge, of course, you can choose better and more expensive mold steel (718 or H13) to make junction box mold. Although the unit price of the mold is high, the relative production cost of the product will be lower.
