Connector molding is the process of making connectors through injection molding. Usually, connectors are tamper-proof and robust. You can not easily disassemble them. With regular injection molds, it’s challenging to give such shapes. It typically requires special connector molds.
Connector molding produces strong, accurate connectors by using plastic and heat. It mainly helps shape small components that you will later use to connect wires, cables, and devices. Connector injection molding uses a connector molding machine to melt plastic and inject it into the mold. When the plastic cools, it becomes a solid connector with the exact shape. The process is fast, clean, and precise.
At GBM, we specialize in connector molding for various industries. Our connector parts are specially made for the automotive and medical industries. Among our main products, plug mold connectors are among the most common. These connectors are typically used in phones, cards, machines, computers, and many everyday products.

The world of connectors is huge. There are thousands, if not millions, of connector types used across various industries. The manufacturing method for each type may differ. And that’s where different types of connector molding methods appear. Even multiple methods can do the same kinds of connectors. To improve strength, durability, and long-term success, you must choose the proper process.
This connector molding method is ideal for simpler projects. These molds can perform a single molding cycle. It is fast, stable, and very suitable for high-volume production.
Insert molding joins metal and plastic parts in a single step. First, the metal terminals are placed inside the mold. Then, hot plastic is injected around them. When the plastic cools, it locks tightly to the metal.
Overmolding allows you to add a protective layer over a connector or cable assembly. First, the connector is placed inside the mold. Then, a second layer of plastic is molded around it. This way, you can create better sealing, strain relief, and durability.
This connector injection molding method uses two materials in a single process. The first one forms the connector structure. The second one mainly adds sealing, color marking, or soft-touch features. Both materials play a crucial role in making a strong bond during molding.
Micro molding typically produces tiny connectors. This process generally requires specialized machines capable of producing tiny features and tight tolerances. It mainly deals with materials such as LCP and PEEK.
For this connector molding, high-tech polymers like PPS, LCP, and PEEK are used. These materials are ideal for high-current setups that produce high heat. They are also suitable for use in harsh conditions.
We follow strict quality standards, including ISO 9001 and ISO 14001. All materials GBM uses meet UL, RoHS, and REACH standards. At GBM, every mold and molded part undergoes pull tests, heat resistance tests, and size checks. Quality is guaranteed.
Unlike regular molding, connector molding often needs a controlled setup. To ensure the same high quality every time, GBM must keep modern machinery. Skilled operators also play a crucial role here. Every step we take here in GBM is precise and results in almost zero defects.
We start by discussing your requirements. The discussion phase may continue until we arrive at the 100% approved design. Once the design is approved, we begin making the prototype. Once you approve the prototype, we create the Mold and adjust it based on the molded parts testing results.
We select the right plastic and dry it to exact specifications. Most of the time, we choose materials based on our customers’ demand. Drying plastics typically ensures smooth flow and proper adhesion.
Once the material is prepared, the GBM operators set up the injection machine. Based on the materials we are working with, we set the temperature, pressure, and cycle time. This whole process is fully controlled, so setting the correct parameters is essential.
Before we put the metal pins into the connector molding machine, we first clean and check them. It is also necessary to put them correctly. The correct position is necessary for the proper electrical connections.
The operator runs a few test shots to verify the size and the quality. If he needs any adjustments, he can make them before starting mass production. Only desired first articles move forward.
The machine then runs full production. During this time, GBM operators carefully monitor the whole process. Overmolding, if needed, is done in a second shot. Every piece here at our factory meets the same high standards.
Each part we create in our connector molding press, we check and test it. We check for the dimensions, visual quality, and mechanical performance. We ship only those parts that pass the final tests.
After they are finished, the connectors are cleaned, packed, and labeled. During our discussion session, we will also confirm which packaging style you prefer. Our engineers will tell you which is the best choice for full protection. Most importantly, we guarantee the fastest and best service possible.
In the electronics industry, connector molding is very important. It is typically used to make pins, housing, and other connectors. In fact, accuracy is crucial here. We offer a wide range of solutions for sensors, switches, and many others.
PC Boards, Metals, Plastics
Molded connectors are attached directly to PCBs, metal frames, or plastic assemblies. Housings, pins, and headers fit tightly.
Nano Connectors
Miniature housings, micro pins and shells, perfect for smartphones, medical instruments, and mini electronics
Thermoset or High Heat Applications
High-heat connectors use thermoset plastics. Housings, terminals, and insulators resist extreme temperatures. These are ideal for auto and industrial use.
Multi-pin Connectors
Molded housings, pin arrays, and guides keep pins aligned. These connectors are widely used in automotive, industrial, and telecom systems.
Sensors
Molded housings and terminal pins ensure secure signal paths. It is applied in temperature sensors, motion detectors, and industrial sensors.
Terminals and Switches
Molded terminals and switch connectors provide durable connections. Housings, contacts, and actuator guides secure electrical pathways.

It might be challenging for you to choose the right material for your project. It typically has a big effect on how molded parts work and how long they last. It also tells you how reliable they are in the long run. Some molded parts may need to handle high heat. On the other hand, some may need to be tested with salt spray for a long time.
Some connectors have very complex shapes, while others are made for regular use. Therefore, when you select the material for connector injection molding, pay attention to the following factors:
You can find custom connectors from the suppliers who specialize in connector injection molding. In this case, you can look for companies that do connector molding as one of their main businesses. Actually, there are different kinds of connectors. RF, electrical, hybrid, and fiber optics may all be part of it.
GBM Mold is an expert in four main types of molding work. We offer general molding, insert molding, connector molding, and unscrewing molding.
When you use classy injection molding, you usually get clean, high-quality connection parts. It relies on tight tolerances, smooth surfaces, and results that are always the same. For electrical and signal efficiency, these traits are necessary.
A classy molding process needs skilled workers, good materials, and strong process control. It needs to focus on reducing flaws and making sure that the part shape stays stable. This process is ideal for terminal housings.
At GBM, we can produce plastic injection-molded terminal block connectors. These connectors typically need a stable size, strong insulation, and a secure fit with metal terminals. The molding process must be carefully controlled for temperature, flow, and pressure.
To make these connectors, GBM typically uses materials such as PA66, PBT, or PC. Each terminal block must meet strict electrical and mechanical standards. We can also handle accurate and automated insert placement. We can also deal with multi-cavity tools and mass production.
Insert molding and overmolding are two different molding processes. Insert molding places a metal insert into a plastic part. You may think of a terminal or a pin. The use of metals typically makes the connector strong. Insert molding also ensures that the metal and plastic bond perfectly.
Overmolding, on the other hand, adds a second layer of plastic to the first component. You may think of cable connectors, strain relief, and soft touch surfaces. Insert molding primarily focuses on combining two materials in a single shot. However, overmolding primarily focuses on protection and added functionality.
