Mechanical Fastening

Mechanical Fastening

Ehren-Haus offers mechanical fastening as one of the methods used for bonding and assembly. Mechanical fasteners include simple and widely used parts such as nuts, screws, pins, rivets, and so on. Just like metals, the mechanical fastening of plastics has also gained traction.

What is Fastening Plastic?

Most methods of fastening plastic are based on the type and size of the plastic parts to be joined. Mechanical Fastening is one of the simplest yet the most efficient ways for joining plastic. Mechanical fastening requires the plastic to be robust enough to withstand the assembly strain and service load. This technique is primarily applied in case of light and flexible assemblies which have a low to medium load. Also, it is more suitable wherein the level of precision required is low to medium. Fasteners could be of threaded, glued, or push-in types.

What Sets Ehren-Haus Apart?

We are capable of offering you the required levels of precision and tolerances. We make structurally robust and intricate designs if required. We offer end-to-end solutions right from the requirement gathering stage to assembling. We also accept your designs in certain file formats and are open about clarifying each design aspect with you. We offer customized mechanical fastening for plastics to help you match your exact requirement in terms of size, shape, dimensions, tolerances, and so on. The team of experts at Ehren-Haus is there to offer you the required end-to-end technical assistance right from the material selection.

What is Our Process?

We accept designs in IGS, CAD, and DXF formats. The designs are analyzed and discussed with the client for clarity. Any design changes are suggested in the initial stages. The prototype building begins after seeking their approval.

    Ehren-Haus’ Capabilities Pertaining to Mechanical Fastening of Plastics

    We offer permanent as well as non-permanent fasteners. These are our mechanical fastening capabilities for plastics:

    Technical expertise

    Our team has experts who can design with respect to your requirements, operational environments, weather, usage of chemicals, loading capacity of the assembly, and so on. The team also has experts in geometry and design including disassembling which is also an important aspect considering the demand for compact materials and spaces. In this stage, we ensure to involve the plastic part supplier, retailer, and our designer. This facilitates a better transition from the design stage to the finished part.

    Materials used

    We efficiently use thermoplastics such as polyamides, ABS blends, weather resistant polymers, PBT blends, and so on to get the right and robust joint.

    Techniques

    Our techniques such as mechanical fastening, adhesive bonding, metal inserts, electromagnetic welding, snap fits, and so on comply with industry standards.

    Joining multiple parts

    We are capable of joining multiple parts required in a design as complex as an automotive part.

    Testing and inspection

    We are very particular about our quality standards and hence all the parts joined through mechanical fastening undergo stringent testing and inspection techniques to check the size, materials, dimensions, functionality, and so on.

    Threaded and unthreaded fasteners

    We recommend molded-in threaded thermoplastic fasteners in case the joints are permanent and the structure is not required to be dismantled. This is because in case of frequent dismantling, it may damage the threads and increase the cost of molds.

    Self-tapping fasteners

    We offer detachable connectivity through our mechanical fasteners such as self -tapping screws commonly used to connect electrical and electronic devices.

    Prototyping

    This is an essential aspect of manufacturing today as it makes the product cost effective, and enables to produce multiple copies of the same product with an equal amount of precision in sizes, dimensions, and so on. It also helps increase the time to market for your products. Needless to say, we are experts in the same.

    Fastener features

    The head of a fastener is an important feature because of the tensile stress it produces. Hence, we recommend round heads for screws and bolts rather than conical heads as the former reduce the stress. We also ensure the distance requirements between the fastening hole and the plastic part’s edge are met as required. Usually, this distance is equivalent to the diameter of the hole.

    Benefits of Mechanical Fastening

    Here are some advantages of using mechanical fastening as one of the joining techniques for your plastic part:


    Automated

    This technique can be performed manually or with the help of a robot depending upon the level of automation you require and can afford.

    Reliable

    You do not need too much of space to perform this task. You do not need to specially prepare any mating surfaces.

    Combination

    This technique can be combined with adhesive bonding for improved results in terms of strong welds, flexibility, seals, and so on.
