In the field of medical injection molding, the polishing process of molds is not only crucial for the external appearance and texture of products but also essential to ensure smooth mold release and avoid defects. Dongguan Yize Mold Co., Ltd., as an expert in precision mold design and manufacturing, understands the importance of medical injection mold polishing. Below, Yize's editor will provide you with a detailed overview of the key points for attention in medical injection mold polishing, helping to enhance the quality of your products.

I. Preparation Before Polishing

Medical injection mold polishing serves a dual purpose: on the one hand, it enhances the surface finish of the mold, giving the product a refined appearance; on the other hand, it ensures that the mold is easy to release, avoiding product adhesion. Before starting the polishing process, the first step is to carefully inspect the new mold cavity and thoroughly clean the surface with kerosene to ensure that the oilstone does not lose its cutting efficiency due to contamination, laying a solid foundation for subsequent polishing.

II. Key Points During the Polishing Process

1. Sequence Principle: When facing a new mold, follow the "first difficult, then easy" polishing principle, especially for hard-to-reach corners and deep bottoms, which need to be processed first to ensure the uniformity of the overall polishing effect.

2. Handling of Combined Parts: For molds composed of multiple parts, it is recommended to polish the coarse or spark textures of each component separately first. Once all components meet the requirements, they are combined for overall smooth polishing to ensure seamless joints.

3. Flatness Inspection: For large flat or side flat workpieces, after removing the coarse texture, a straight steel plate should be used for light transmission inspection to promptly detect and correct any unevenness or undercuts that could lead to difficult mold release or product damage.

4. Protective Measures: To avoid undercuts or damage to mating surfaces during grinding, saw blades can be attached or sandpaper wrapped around the edges for precise protection, ensuring the mold remains intact.

5. Operating Techniques: When polishing flat surfaces, keep the oilstone handle as horizontal as possible and move it back and forth, with a tilt angle of no more than 25°. A larger tilt angle can cause downward force, leaving unnecessary coarse textures on the workpiece surface.
