What is plastic injection molding process?
Plastic injection molding is a manufacturing process in which melted plastic is injected into a mold and then cooled to form a solid part. The mold is created from a metal or plastic tool (1.2344, H13, NDK80, etc.) and is typically made in two halves that are clamped together. The plastic material is heated in a barrel and then forced into the mold under high pressure where it cools and solidifies into the desired shape. This process is used to produce large quantities of identical parts with high precision and repeatability.
When do you need plastic injection molding service?

Thin Wall injection molding: it permits a precise, very accurate molding of plastics and gives better details to the product. This is the name referring to products with a wall thickness lower than 2mm. Usually, the flow is quick, permits a short cycle time and a cost-saving.
Hot runner mold: the special process of injection of plastics where the plastic is kept hot when going through cavities of the mould while the rest of the mould is getting cold to solidify the plastic part and create the molded part: this permits to save plastic material. This is mainly used for parts with medium or large sizes. We are used to working with all popular companies like Yudo, INCOE, Synventive, Husky, HRS… We also have the technology to make our own hot runner systems if the production of the parts (Molding) is made in-house. This again allows our customers to save costs.
Optical Lens Molding: precision molding for glass plastic. This is the technique to produce transparent plastic molded parts (For example Security cameras parts such as the dome cover or also phone frames).
Gas-assist Injection Molding: the plastic parts are gas-assisted molded which means that gas (Most often is nitrogen) is injected at the final stage of the part creation process. It permits to reduce the cycle time, the product weight, the risk of deformation and also the pressure tons injection needed. Moreover, it makes the part’s structure stronger with a better look.
LED/LCD frame molding: injection of plastics used for example to manufacture television screen monitors, computer back-light modules, GPS frames…
IMD, IMF, IML, IMR Molding: In-mold decoration. The decoration of the part is made inside the mould through a film. The film is printed before the molding with the designs wanted. It permits better productivity and extends the decoration’s lifetime. If the customer wants to change the design/decoration of the part, it is not necessary to make another mould but only to change the film. SINCERE TECH is experienced with In-mould forming, in-mold-labeling, and in-mold by roller.
Overmolding: this technique permits to join several components together with a thermoplastic material. This reduces assembly and labor costs. Because the parts are made together, this allows less risk of improper termination or misalignment and increases the design flexibility. Moreover, thermoplastic provides better resistance to vibration or shocks. This technique permits to increase resistance, reduce costs and weights.

Types of Plastic Molds
There are various kinds of plastic molds available; each of them has special uses. We’ll look at a few of the most often used plastic mold types on the market.
injection molds: injection molds are the type of plastic molds that are utilized in the world of business the most frequently. Manufacturers use them to produce a wide range of plastic products, such as home items, electronic components, and automobile parts. The stationary half of an injection mold and the moving half of the mold simultaneously clamp together during the molding process. We apply high pressure to inject molten plastic into the mold’s cavity, allowing it to cool and harden to take on the desired shape.
Blow molds: Bottles, containers, and tanks are just a few examples of the hollow plastic goods made with blow molds. In order to get the plastic to expand and take on the shape of the mold, air is injected into a parison, which is a hollow tube filled with molten plastic, inside the mold cavity. We can construct blow molds from a variety of materials, including steel, plastic, and aluminum, depending on the need.
Compression Molds: Compression molds produce plastic items with exceptional precision and strength. The mold cavity receives a heated plastic sheet or pellet, which undergoes intense pressure compression to assume the desired shape. Manufacturers widely use compression molds to produce intricately designed products with precise dimensions, like parts for automobiles and aircraft.
Rotational Molds: Also known as rotomolds, these molds create large, hollow plastic objects such as playground equipment, tanks, and containers. The procedure entails heating the mold chamber and turning it in two perpendicular directions so that the molten plastic coats the mold’s internal surface uniformly. Rotational molds are incredibly adaptable and can create intricate shapes with consistent wall thickness.
Thermoforming Molds: Manufacturers use thermoforming molds to create goods with thin plastic walls, such as clamshell containers, packaging trays, and disposable cups. A mechanical plug or vacuum pressure helps form a thermoplastic sheet over a mold cavity after heating it until it becomes malleable. Molds for thermoforming are economical and appropriate for large-scale manufacturing.
Various industries suit different types of custom plastic molds, each with its own unique advantages and limitations. A plastic mold maker can help you choose the best mold according to your project. If you do not know what type of mold you should use, contact us for a quote, and we will offer you a suitable mold type to suit your project.
