There are multiple solutions for the assembly of plastic parts, but few of them meet all the possible application requirements. Let our experts give you their advice.
The screws for the plastic components in a car represent a large percentage of its total number of fasteners. Some of its elements such as the instrument panel, headlamps, mirrors, door modules or bumpers include different types of screws for plastic to hold the different parts together and withstand the necessary loads.
The automotive industry is the third largest industry after packaging and construction for plastic consumption.
Plastics perform from the engine to the chassis; throughout the interior to the exterior, replacing traditional materials like steel and glass and contributing to vehicle weight reduction. Nowadays, plastics make up approximately 50% of the volume of a modern light vehicle but less than 15% of its total weight.
PP, ABS, PC and PA are some of the most common thermoplastics used for automotive components, where the joints are submitted to vibration, thermal shock and high mechanical loads.
