Wall Thickness
Maintaining uniform wall thickness is essential for ensuring consistent cooling and preventing warping in injection molded parts. Uneven wall thickness can lead to variations in cooling rates, causing internal stresses and dimensional inaccuracies.
Recommendations:
- Aim for a consistent wall thickness throughout the part.
- Avoid abrupt changes in wall thickness.
- Use gradual transitions to minimize stress concentrations.
- Typical wall thickness ranges for pet products: 2-4mm.
Ribs and Gussets
Ribs and gussets are structural features that add strength and rigidity to parts without increasing wall thickness. They are particularly useful in areas that are subject to high stress or require additional support.
Recommendations:
- Use ribs to reinforce thin walls and prevent bending.
- Place gussets at corners and intersections to increase stiffness.
- Design ribs with a thickness that is 50-60% of the adjacent wall thickness.
- Ensure proper draft angles on ribs and gussets for easy ejection.
Draft Angles
Draft angles are the degree of taper applied to the sides of a part to facilitate easy ejection from the mold. Without draft angles, the part may stick to the mold, causing damage or ejection problems.
Recommendations:
- Apply a draft angle of at least 1-2 degrees to all vertical surfaces.
- Increase draft angles for textured surfaces or deep cavities.

5. The Injection Molding Process: A Step-by-Step Guide
Clamping
The injection molding process begins with clamping. The mold, typically made of two halves, is securely closed by the clamping unit. This unit applies sufficient force to keep the mold closed during the injection phase, with clamping force requirements varying based on the part’s size and the material being used. Accurate alignment of the mold halves is crucial to prevent defects such as flash.
Injection
Once the mold is clamped, the injection phase begins. Plastic resin, in pellet or granule form, is fed into the injection molding machine. This resin is heated and melted into a liquid state. The molten plastic is then injected into the mold cavity through a sprue, runner system, and gate under high pressure. Precise control of injection speed and pressure is essential to ensure the mold cavity is filled completely and evenly, minimizing defects like voids or sink marks.
Dwelling
After the injection phase, a dwelling or holding phase follows. During this stage, the injection pressure is maintained to compensate for material shrinkage as the plastic cools. This ensures that the part retains its intended dimensions and shape. The duration of the dwelling phase depends on factors such as the type of plastic, part thickness, and mold temperature.
Cooling
Cooling is a critical phase in the injection molding process. The molten plastic must cool and solidify within the mold cavity before ejection. Cooling channels within the mold circulate water or other cooling fluids to regulate the temperature and promote uniform cooling. The cooling time is influenced by the material’s thermal properties and the part’s geometry. Inadequate cooling can lead to warping or other dimensional issues.
Ejection
Once the plastic has sufficiently cooled and solidified, the ejection phase begins. The mold opens, and the ejection system, typically consisting of pins, blades, or air blasts, pushes the part out of the mold cavity. Proper ejection is essential to prevent damage to the part. After ejection, the mold closes again, and the cycle repeats.
Table: Injection Molding Process Parameters
| Parameter | Description | Importance |
|---|---|---|
| Clamping Force | Force applied to keep the mold closed during injection | Prevents mold separation, ensures part accuracy |
| Injection Pressure | Pressure used to inject molten plastic into the mold | Fills the mold cavity completely, minimizes defects |
| Injection Speed | Rate at which molten plastic is injected into the mold | Affects surface finish and internal stresses |
| Melt Temperature | Temperature of the molten plastic | Influences material flow and part properties |
| Mold Temperature | Temperature of the mold | Controls cooling rate, affects part dimensions and surface finish |
