Surface Finishing  – Polish / Texture

Surface treatment is critical in plastic product manufacturing, with polishing and texturing being key techniques. Polishing smooths the product surface, eliminating flaws and scratches to enhance appearance and gloss. Texturing creates specific visual and tactile effects, often used for automotive interiors or electronic casings where both aesthetics and functionality are essential. 

Parting Line Design

In mold design, parting lines, and slider lines play a key role in the injection molding process. Red is the parting line, blue is the slider line

Draft Angle Analysis

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 

Slider and ejector designs are key components used in mold making, especially in the injection molding process. Their role is to allow the manufacture of plastic parts with complex internal or external geometries, as well as to handle protrusions or hollow structures in the front bumper product. Blue lines are parting lines of sliders. 

Ejector Design

The ejector design is critical in plastic injection molding for the smooth removal of the molded plastic part from the mold.

Gate Type & Location & Size

The mold incorporates a 5X YUDO thermal system (5IP) with five independently controlled temperature zones and valve gates for sequential action, paired with cold runners and tunnel gates. This hot runner system ensures complete melting and smooth flow of the plastic material, while precise temperature and valve control allow for fine-tuning of the injection process, ensuring part quality and consistency. The cold runner and tunnel gate design reduces cooling time and internal stress, enhancing both production efficiency and the quality of the finished product.

Problem Points of Front Bumper

The yellow side is the visible side. Although the mold pulling angle of only 0.3 degrees can make the demolding smoother, this angle may actually lead to the appearance of drag marks. Therefore, it is recommended to increase the pull-out angle to 1 degree, which can effectively reduce or avoid the appearance of drag marks, thus improving the surface quality and overall appearance of the molded parts.

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.
