When Zhongyu manufacturer produces the Injection Molding PP Cabinet with IML Label, it embeds high-definition patterns into the injection molding process, adapting to the special contour of the reserved handle gap of the cabinet, balancing the color reproduction of the complex patterns and the molding yield. It provides a complete set of technical implementation support from pattern process evaluation, film material customization to large-scale delivery to home product factories.


Adapting to the special structure of the hollow handle
- High saturation complex patterns are restored
- The printing layer has a built-in protective structure
- Adapting to the PP cabinet and molecular integration
- Balancing appearance and recyclability
- Adapting to multiple environmental conditions for durability
1. Gravure printing on PET/PP film and Lamination
2. Cutting into standard label sheets
3. Automatic robot places labels into injection mold cavity
4. Plastic melt injection, film and plastic melt into one piece
5. Demold finished IML plastic products directly
1. Hollow handle panel, traditional stickers are prone to shifting and wrinkling; One-piece injection molding of PP cabinet with IML Label ensures precise pattern alignment.
2. Ordinary sticker printing with multiple layers of contrasting colors is prone to losing dots and color deviation; Thick film high-precision printing restores the original color of complex patterns.
3. The handle is repeatedly pulled, self-adhesive easily comes off; IML is fused with the cabinet body, eliminating the risk of force-induced detachment.
4. Ordinary sticker adhesive layers are difficult to separate, limiting recycling; IML film material is the same as PP, adapting to overseas recycling standards.
5. Large-shaped panels with irregular gaps, common film materials are prone to material breakage and shift; Optimizing the film cutting based on 3D drawings reduces wrinkling defects.

|
Cut-out handle hole adaptation |
Custom die-cut according to cabinet 3D drawing, optimize edge overflow risk |
Only support regular flat panel, no targeted optimization for hollow position |
Manual pasting, high offset risk around hole |
|
Complex multi-color pattern reproduction |
Support high-saturation multi-layer ethnic pattern, retain tiny line details |
Suitable for simple color block patterns, complex patterns easy to lose details |
Limited by surface printing, color stacking effect is poor |
|
Stress resistance of handle area |
Integrated fusion, resistant to repeated pulling stress |
Ordinary film, easy local delamination at stress position |
Edge warping frequently occurs after long-term use |
|
Recycling compliance for export |
Same material as PP cabinet, no separation required |
Partial film material incompatible with PP |
Adhesive glue belongs to foreign impurities, difficult for recycling |

Answer: We will optimize the die-cutting boundaries based on the 3D model of the cabinet to avoid the risk of injection molding overflow in advance.
Answer: Yes, we will make process corrections to the draft to ensure that the pattern does not deform after molding.
Answer: We need the 3D drawings of the cabinet and the original design draft to facilitate our complete process assessment.
Answer: The products can comply with export compliance standards and we can provide corresponding detection-related materials.
Answer: Yes, we can first conduct small-scale verification of the injection molding effect and then start the large-scale order.
Answer: Printing and die-cutting are all completed in our own workshop. Key processes are not outsourced, and batches can be traced.
Answer: After receiving the drawings, we evaluated the membrane material adaptation plan and provided suggestions for optimizing the large panel molding process.
