Precision injection molding excels in producing parts with high repetition accuracy. Repetition accuracy refers to the consistency of dimensions and properties across multiple parts. In precision injection molding, product weight deviation is minimal, typically less than 0.7%. This means that each piece emerging from the mold closely matches the one before it. This level of consistency is crucial in industries where reliability and uniformity are paramount.

The medical industry relies on precision injection molding to create life-saving and life-improving devices with stringent quality standards. Applications include:

This category necessitates a straightforward mold, often crafted from cost-effective materials like aluminum or 3D-printed materials. Additionally, it requires minimal raw materials and less advanced machinery, resulting in an overall low injection molding cost. However, the cost per unit part tends to be higher in low-volume production scenarios.

Injection Speed Control: Controlling the speed at which molten material is injected is crucial for avoiding defects. Precision machines allow for fine-tuned control of injection speed.

As we know, injection molding mold and machine are two key components in the injection molding process. Compared with traditional injection molding, precision injection molds, and machines have higher standards. In the next parts, we will learn what are the special requirements for precision injection molding molds and machines.

While high-performance plastics may offer specific advantages, they often come with a higher price tag. Analyzing the functional requirements of the part and selecting a cost-effective material that meets those needs can lead to substantial cost savings without compromising quality.

The injection mold structure and design directly influence various aspects of the final product, including its dimensional accuracy, surface finish,

Precision Machining: Molds are created using advanced machining techniques, including CNC (Computer Numerical Control) machining. This precision ensures that the molds’ cavities and details are reproduced accurately, down to the finest tolerances.

Determining whether injection molding is expensive isn’t a straightforward answer. While the process proves cost-effective for mass production of plastic parts, the initial setup costs can be substantial due to high machine prices.

Insert molding involves placing pre-formed components or inserts into the mold before injection. This technique allows for the integration of multiple parts into a single molding process, reducing the need for additional assembly steps. Naturally, a single-step process would mean a lower machine run-time and a lower number of repetitions and cycles. Furthermore, you won’t be assembling separately designed parts together as well and that again would save time. By consolidating manufacturing steps, insert molding can lead to time and cost savings.

Surface finishing includes processes such as annealing, sandblasting, powder coating, etc., in which the part is subjected to increase its aesthetic appeal or functionality. They are separate from the injection molding process itself. However, many service providers will give a discount to clients using them for both injection molding and surface finishing. Also, there are secondary services which can be manufacturing processes(e.g., machining and drilling), assembly services (e.g., sonic welding), and decorating (e.g., pad printing), which can increase the injection molding cost.

To simplify mold designs, it’s crucial to eliminate unnecessary features, optimize part geometry, and consider using standardized components. Utilizing CAD and CAM tools can help in identifying and removing superfluous elements, ensuring efficient mold design without compromising product quality.

This approach simplifies the mold design, leading to lower manufacturing costs as complex molds are more expensive to produce. Furthermore, reducing part complexity translates to decreased material usage, offering direct savings. Additionally, simpler designs can shorten the molding cycle, boosting productivity and cutting down on labor and energy expenses. This also results in molds that are less demanding in terms of maintenance. Importantly, such streamlined designs often yield parts with improved structural integrity and consistent quality, reducing the likelihood of defects.

Several factors directly impact your costs, and understanding these key elements is crucial for optimizing your project’s financial aspect.

Precise Positioning Between Templates: In multi-cavity molds or molds with moving parts, precise positioning between templates is essential. This ensures that each part produced is consistent and free from defects.

Part inspection costs can be specialized or standard. On the one hand, standard inspection is an internal process that requires trained personnel to check for part defects (cosmetic or critical) and a quality verification team to identify the probable cause. On the other hand, specialized inspection involves inviting specialized engineers to inspect the product. Thus, specialized certification costs more, and sometimes injection service providers offer the certification at a cost.
