Air Curtain On Vehicles

Surface Finishing of Air Curtain– Polish / Texture

Surface treatment plays a vital role in the manufacturing of plastic products, with polishing and texturing being two common techniques. Polishing is to make the surface of the product smooth and even, remove possible flaws and scratches, and improve the appearance quality and gloss of the product. Texturing is usually used to produce products with specific appearance and feel requirements, such as automotive interior parts, electronic product casings, etc.

Parting Line Design of Air Curtain on Vehicles

When designing the product DFM, our designers take into consideration the mold formability, demolding shrinkage and deformation, structural strength, design style as well as the subsequent processing and assembly to ensure the molding quality and production efficiency of the product. Red is the parting line.

Draft Angle Analysis of Air Curtain on Vehicles

Draft angle analysis is a critical step in the design of plastic products to determine if the product geometry is suitable enough for mold making so that the molded part can be smoothly removed during demolding.

Slider & Lifter Design of Air Curtain on Vehicles

Slider design is an important aspect in the manufacture of injection molds, which involves the precise arrangement of sliders in the mold structure and the design of corresponding slide trajectories and channels to achieve specific shape or structural requirements in the product.

Sub-Insert Design of Air Curtain on Vehicles

Sub-Insert is a key component of a mold, used to form the interior or sidewall structure of a product. It is usually used to manufacture products with complex shapes, such as automotive parts, appliance housings, etc.. The design of the sub-insert has a direct impact on the molding quality and productivity of the product. The pink line is the slider insert line.

Ejector Design of Air Curtain on Vehicles

The air curtain mold design incorporates ejector pins of varying diameters to address different demolding needs. Blue Ø5 pins are used for smaller or intricate sections, yellow Ø8 pins for medium-sized areas, and dark red Ø10 pins for larger or more complex regions. By matching pin diameters to part geometry and requirements, the design ensures efficient demolding, stable mold performance, and high-quality part integrity. This tailored approach reflects a practical understanding of balancing precision and durability in mold engineering.

Gate Type & Location & Size of Air Curtain

The mold is based on the professional design of the YUDO hot runner system, and we used 2 valve gating to ensure that each part is precisely filled and molded during the injection process. For the red surface, we designed a 6x4mm with 0.5 deep dimple for gating to define the injection gating position. In addition, we used a banana gate with dimensions of 1.2×2.6 mm. This gate design is intended to achieve uniform flow and distribution of the plastic material, thus ensuring dimensional accuracy and surface quality of the molded part.

Reasonable mold layout design needs to take into account factors such as the injection molding machine, mold, cooling system, operating space and molded product removal to ensure the efficient operation of the production process and the quality of the final product.

Before delivery, we will fully maintain and clean the molds to make sure the surface of the molds are smooth and internal impurities. Then anti-shock material and protective padding are packed and put into wooden crates and labeled with model and quantity information.
