The essence of insert molding lies in the “precise combination of heterogeneous materials”, with the core logic revolving around three key steps: “positioning – cladding – bonding”. The insert needs to be fixed by the positioning mechanism inside the mold to ensure no displacement or tilt during the injection molding process, providing a precise benchmark …
Medical-grade silicone offers several benefits that cater to the challenges of complex designs in medical devices:
Material cuttingCut the rolled film into square blocks of the designed size for subsequent printing and molding processes. The precision and dimensions of the cutting are crucial for the smooth progress of subsequent processes; Offset printingCreate a film screen based on the required icons and text, and print on the cut square film blocks. During …

Injection molding Cycle time refers to how quickly a tool can make one part. Injection molding Manufacturers often coat tools to improve speed and durability. Coating Type Benefits Chrome/Nickel Plating Corrosion resistance, moderate hardness PVD (Physical Vapor Deposition) High hardness, wear resistance CVD (Chemical Vapor Deposition) Strong bonding, better for higher temps Use coatings when …

Manufacturing tools must resist wear, stress, and environmental factors. Designers select tool materials based on: Common tooling materials include: Material Typical Use Advantages Limitations Steel (H13) High-pressure die casting molds Good toughness, heat resistance Higher cost, longer lead times Tool Steel Cutting tools, dies Excellent wear resistance Prone to chipping if not treated Aluminum Low-volume …
Designing a manufacturing tool involves multiple stages. Teams can follow this workflow: Throughout this tooling design process, clear communication between designers, manufacturers, and end users helps manage expectations on cost, timing, and performance.
Injection molding defects refer to undesirable phenomena in the appearance, dimensions, structure, or performance of plastic parts during the injection molding process, caused by factors such as materials, processes, equipment, or operations. These defects may manifest as surface roughness, dimensional inaccuracies, internal voids, or inclusions within the plastic parts. Injection molding defects not only affect …
Voids are mainly manifested as cavities or bubbles inside plastic products, which may be caused by plastic not completely filling the mold cavity during the injection molding process. According to different manifestations, voids can be: Vacuum VoidsDuring the injection molding process, vacuum voids are caused by the plastic surface contacting the low-temperature mold wall during …
When the color of plastic molded parts is incorrect, it directly leads to uneven color or significant differences in color depth within a product or batch of products. This discoloration typically occurs in specific stripes on the molded product and is manifested as color differences, jetting marks, black spots, or impurities. Causes of DiscolorationThe material …
This type of defect typically manifests as numerous very small blister within the finished product, often accompanied by silver streaks. When observing the product externally, these blister typically appear as circular bright spots. For precision plastic injection molding products with waterproof performance requirements, even a tiny blister can lead to the entire product being returned …
