We have to remove a brand new windshield to replace all the New trim clips made by a popular vendor. They're so brittle they all break as soon as you try to install the trim. (IMG:style_emoticons/default/WTF.gif)
More than 3 hours of labor generated by using substandard parts. Seems unfair to charge my customer and I'm not happy about eating that either, except that I'm the one who recommended the vendor. Never again. (IMG:style_emoticons/default/dry.gif) Buyer beware. I'm going back to Genuine Porsche. |

I’ve been in the plastic injection molding industry for 36 years. Some of things I would look at is the same material being used. Are you using recycled materials or too high of a mix of reground material. Also compare where the OEM part is gated to your part. Direction of flow will determine part strength. Material can become degraded if it is being processed in to large of a machine. PM me if you have questions or can’t find a cause. I would be glad to look at some parts for you.

We had a poor supplier that made polypropylene tubs that were as fragile as glass instead of being tough. |
