At TX Mold, we understand that each project is unique and may require different injection molding approaches. This is why we have invested in top-grade equipment and a team of professionals that is fully trained in overmolding techniques. Our team comprises designers, mold engineers, and production engineers that all work in harmony. This ensures that each product and mold design is optimized for overmolding and that the resin materials that are chosen are ideal.
Overmolding is applicable in a variety of industries. Currently, we offer overmolding services to home appliance, automotive, furniture, bucket, and baby product industries and many others. We also serve both local and overseas clients spread across different parts of the world.
Overmolding is a step two-process that, in some instances, may also require the use of more than one type of resin. As a result, it requires careful attention during execution as well as in the mold and product design stage. We are experienced overmolding professionals that offer these and other advantages such as:
Reduced Assembly Costs: We offer seamless overmolding for parts that require the use of different resin materials to achieve improved stability or structural features. It is much cheaper than molding the parts separately and then assembling them at a later stage.
Flexible Use of Material: The thermoplastic materials used in overmolding have to be compatible. Our team of design and engineering experts have all it takes to advise you on different material options based on your budget and the desired finished product.
Completion of Complex Parts: The FOW Mould factory facility is equipped with the latest overmolding equipment. This, coupled with our exceptionally talented team, enables us to achieve even the most complex designs with precision and on time.
High-Efficiency: Our goal is to help our clients realize high-quality products while also maintaining profitability and running their businesses on schedule. To this end, we design product parts and molds that are highly optimized for the overmolding insert molding process. They are tested also for manufacturability and all-round production efficiency.
Overmolding is a unique injection molding process that is used for making seamless combinations of several materials into a single part or component. Its highlights can be summed up as below:
Insert molding, on the other hand, is defined as a variation of injection molding techniques that involves the insertion of a metal part into a mold before the actual injection molding. It can best be described as in the summary below.
The overmolding injection molding process is a straightforward process. It is performed as explained below.
Overmolded structures are often larger than typical injection molding parts. Their designs are equally more structurally complex. More so due to the fact that they may involve the use of different materials that shrink at different rates. Precision is, therefore, very important when developing mold designs for overmolding processes.
TX Mold has worked on numerous overmolding projects and we have perfected our skills through these experiences. We take into consideration the part design and the materials that will be used for overmolding, right from the start. This enables us to design molds with precise dimensions, draft angles, and high tolerances. We further test each mold design to ascertain its accuracy. Subsequently, our clients are able to realize quality overmolded parts because all their manufacturing needs are anticipated and addressed accordingly.
Material options are fundamental in overmolding. First, the chosen materials have to be suitable for the part being produced. Secondly, where more than one thermoplastic material is being used, the materials have to be compatible. Our in-house production engineering team is well-versed in resin compatibility. We also test materials to ascertain their viability with regard to manufacturing and product performance. Our list of material options includes:
Overmolding products are utilized in both domestic and commercial spaces in varying ways. The following are some of the notable plastic overmolding.
Baby products such as toys and furniture are more appealing to children when they are colorful and have interesting shapes. Overmolding helps achieve this by introducing different colors of resins to form a part. It also makes it possible to create seamless designs instead of assembling baby products bit by bit. This is crucial because if small assembled components fall off they would be a choking hazard.
The automobile industry often relies on overmolding when a plastic part needs to be made stronger or its texture needs to be altered to improve its grip. Examples of parts that are often overmolded include dashboards.
Electronic parts are made safer for consumers and more durable by insulating electronic components in plastic. This is because plastic is a non-conductive material. Encapsulating electronic components in plastic can also be used to increase their IP rating. Both insulation and encapsulation can be achieved through overmolding.
Medical equipment has to be designed in a manner that makes it possible to keep it sterile. Durability and operational safety are equally non-negotiable. For this reason, devices such as defibrillators are overmolded in plastic to form a well-encapsulated structure that is lightweight, can easily be sterilized, and strong enough to survive long-term use.
