### 1. Key factors to consider when designing custom injection molding parts.

When designing custom injection molding parts, it is crucial to consider factors such as part geometry, wall thickness, draft angles, undercuts, and gate locations. These factors can significantly impact the moldability, functionality, and overall quality of the final part. It is also important to consider the material selection, parting lines, and surface finish requirements during the design phase to ensure a successful outcome.

### 2. Impact of material selection on injection molded parts.

Material selection plays a critical role in the quality and performance of injection molded parts. Different materials have varying properties, such as strength, flexibility, heat resistance, and chemical resistance. Choosing the right material for your application is essential to ensure the longevity and functionality of the part. Additionally, material selection can impact the cost of production, so it is important to consider both performance requirements and budget constraints when choosing a material for custom injection molding parts.

### 3. Common mistakes to avoid during the custom injection molding process.

One common mistake to avoid in custom injection molding is designing parts with inadequate wall thickness. Thin walls can lead to issues such as warping, sink marks, and poor dimensional stability. It is important to work closely with a knowledgeable mold designer to ensure that the part geometry and wall thickness are optimized for the injection molding process.

Another common mistake is neglecting to account for draft angles in the design. Draft angles are critical for facilitating the ejection of the part from the mold without causing damage or distortion. Failing to include draft angles can result in costly production delays and defective parts.

Finally, it is essential to carefully consider gate locations when designing custom injection molding parts. Proper gate placement is crucial for achieving uniform filling and minimizing defects such as weld lines and air traps. Working with experienced injection molding professionals can help avoid these common mistakes and ensure a successful custom molding process.
