  • Injection of a substanceGenerally speaking, molding is the process of forcing or injecting molten plastic into an existing mold cavity. Mold cavities are formed by injecting plastic resin into a heated barrel, allowing it to cool and harden to the shape of the cavity. Lomont's molding process is well-suited for high- or low-volume production runs, and it is capable of dealing with the challenges of complex geometries.

    Process of Plastic Injection Molding
    The Injection Molding process at Lomont consists of six steps: clamping, plastic injection molding, dwelling, cooling mold, opening, and ejection. Despite the fact that each step presents its own set of difficulties, each step is necessary in order to ensure that your molded parts follow the proper process.

    Preparation of the Clamping Stage
    The mold, the clamping unit, and the injection unit are the three fundamental components of an plastic injection molding company molding apparatus. Because it is so strong, it can hold the two halves of an injection mold together while it is being injected and cooled. Hydraulic or electric pressure is used to apply the clamping force.

    Stimulation of the  Hot Runner Molds Stage
    A hopper located on top of the injection unit receives the plastic pellet material during the plastic injection molding parts phase. The pellets are fed into a cylinder, where they are heated until they become molten, at which point they are removed. An electric screw, also known as a ram, is placed within the heating chamber to mix the molten resin and force it to the other end of the cylinder. The injection process begins once there is sufficient material accumulated in front of the screw. The molten plastic is introduced into the mold through a sprue, with the screw controlling the pressure and speed of the ABS Plastic Molds.

    Dwelling Stage is the final stage of the construction process.
    During the dwelling phase, more pressure is built up within the injection process. Once the molten plastic has been injected into the mold, pressure is applied to ensure that all of the mold cavities are completely filled with the molten material. This portion of the {anchor} molding process contributes to the overall wall thickness of the molded parts.

    Cooling Stage During the cooling stage of the injection molding process, the molded part is allowed to cool properly.
    Time required for cooling varies according to the thickness of the part wall.

    Stage One: Getting Things Started
    As the clamping pressure is released, the mold separates. When this occurs, the mold is split in half, resulting in two halves.

    Stage of ejection
    To remove the finished part from the mold after it has been generated with high strength, an ejection rod and plate are used. All of the unsold sprues and runners can be recycled and re-used in subsequent production runs.

    Advantages of Injection Molding
    The ability to scale production to meet your specific requirements is the primary advantage of injection molding and the overall molding process. The cost per unit during injection molding manufacturing is extremely low once the initial costs have been paid. In addition, as more parts are manufactured, the price of the parts tends to decrease significantly. Other advantages include: waste reduction. Process that is simple to repeat. High rates of production. There is a diverse selection of materials available. Labor is inexpensive. There is very little to no finishing required. Expertise is a must. Lomont's High Pressure Injection Molding expertise includes the following certifications: ISO 9001 Certified. Parts with a Complex Geometry. Conversion of metal to plastic. Controlling the thickness of the wall. Capacity varies from 55 to 2,700 tons.
