Plastic parts are by no means exclusive to any specific industry or purpose. If you can envision it chances are we can create it. Plastic injection molding is a fantastic solution for both small-batch manufacturing and for High-volume production.
A plastic molded part may be the centerpiece of your project, or a small part buried deep within the workings of a complex and larger machine. In every instance, parts begin with a great idea. If you have detailed CAD designs ready to upload or just a simple sketch on a napkin, our designers can work with you to determine the measurements and materials appropriate for your part. Once a design is prepared your mold will be created.
Plastic pellets are filled into molds, superheated, and injected to form a solid mass. Upon cooling, you get a flawless plastic part. Overmoulding adds color, texture, and strength by layering polymers. A mold can produce thousands of units, ready for finishing.
Based on needs, various textures and coatings can be applied for desired aesthetics and functionality. Finished parts are meticulously packaged, shipped, and tracked to ensure prompt, undamaged delivery.
Plastic Injection Molding is the Preferred Process for Creating Custom Plastic Parts for Nearly Any Industry
Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold. It is commonly used with plastics but can also accommodate metals, glasses, and elastomers. The process begins with melting the material, which is then injected under pressure into a mold cavity. Once the material cools and solidifies, the mold is opened to eject the finished part. This technique is favored for its ability to produce large volumes of identical parts with high precision, complex shapes, and excellent surface finish. Injection molding is efficient and cost-effective, particularly suitable for mass production.
Our injection mold-making process includes six essential steps: Step 1: Production Arrangement: We begin by thoroughly understanding all requirements and arranging the production details accordingly. Step 2: DFM Report Analysis: A detailed Design for Manufacturability (DFM) report is provided free of charge. This report helps in conducting a feasibility analysis to ensure the mold will meet all specifications and quality standards. Step 3: Production of the Mold: The mold is put into production. We provide clients with a Tooling Schedule form that outlines the entire cycle, allowing them to track the progress at any time. Step 4: Free Sample Testing: Once the mold is produced, a sample is created and provided to the client for testing to ensure it meets the required specifications. Step 5: Mass Production: Upon client confirmation that the sample meets all quality and functionality criteria, full-scale production commences. Step 6: Mold Saving: After production and a thorough quality inspection, the parts are delivered. The mold is then cleaned and properly stored to maintain its condition for future production runs.
Injection molding is a complex process that involves four key stages to create high-quality plastic parts: Clamping: Before the injection of the material, the two halves of the mold must be securely clamped together by the injection molding machine. This is crucial to prevent the mold from opening during injection, ensuring that the molten plastic does not escape. Injection: Molten plastic is injected into the clamped mold at high pressure. This stage involves packing the plastic into the mold and maintaining pressure to fill every part of the mold cavity completely. Cooling: After the mold is filled, the plastic begins to cool and solidify within the mold’s cavities. The cooling must be controlled to prevent defects and ensure that the part maintains proper dimensions and mechanical properties. Ejection: Once the part has cooled and solidified, the mold opens and an ejection mechanism pushes the completed part out of the mold. The machine is then ready to start a new cycle with the clamping of the mold for the next part.
At Sino Rise, we understand the diverse needs of our clients, which is why we have no minimum order requirement for our injection molding services. This flexibility allows businesses of all sizes to access high-quality molded parts, regardless of the size of their project. While we are equipped to handle orders from a single prototype to thousands of units, it’s worth noting that larger order quantities typically result in more competitive pricing. This volume discount is due to the economies of scale in production, making larger orders more cost-effective per unit. Whether your project is large or small, we are here to provide the best value and service.
