Manufacturing Process of Household Plastic Molds

1. Product and Mold Design

The manufacturing process begins with product design. Engineers define the shape, wall thickness, and functional features of the household plastic item based on usage requirements. Using CAD software, the mold structure is designed accordingly, including cavity layout, parting lines, draft angles, and ejection systems. At this stage, material shrinkage and surface finish requirements are also considered to ensure dimensional accuracy.

2. Material Selection and Preparation

Once the design is finalized, suitable mold steel or aluminum is selected based on expected production volume and plastic material. The raw mold material is inspected and pre-treated, often through annealing, to improve machinability and reduce internal stress before cutting operations begin.

3. Machining and Shaping

CNC milling, drilling, and EDM (Electrical Discharge Machining) are used to shape the mold core and cavity. High-precision machining ensures that complex geometries and fine details are accurately reproduced. For household plastic molds, smooth internal surfaces are particularly important, as they affect product appearance and ease of demolding.

4. Heat Treatment and Surface Processing

After rough machining, heat treatment is applied to improve hardness and wear resistance. Surface treatments such as polishing, texturing, or coating may follow, depending on the desired finish of the plastic product. For example, a matte texture may be applied to molds used for storage boxes to reduce visible scratches.

5. Assembly, Testing, and Adjustment

Finally, mold components are assembled, and trial molding is carried out. Test runs help identify issues such as short shots, warpage, or flash. Adjustments are made until stable production conditions are achieved, completing the manufacturing process.

Differences Between Materials Used in Household Plastic Molds

Different mold materials are chosen based on production needs, budget, and performance requirements. The many common materials include various steels and aluminum alloys. Their differences can be summarized as follows:

Material Type

Typical Characteristics

Common Applications

Cost Level

P20 Steel

Good machinability, moderate hardness

General household items

Medium

H13 Steel

High heat resistance, good strength

Heat-resistant plastic items

Medium–High

Stainless Steel

Corrosion resistance, clean surface

Food-related products

High

Aluminum Alloy

Lightweight, fast heat transfer

Prototypes or short runs

Low–Medium

Steel molds are widely used for mass production of household plastic items due to their durability and stable performance. P20 steel is often selected for daily-use products such as buckets or hangers, as it balances cost and lifespan. H13 steel is more suitable when molding plastics that require higher processing temperatures.

Stainless steel molds are preferred in environments where corrosion resistance and hygiene are important, such as food containers. Aluminum molds, while less durable, offer faster machining and shorter cycle times, making them suitable for product development or limited production runs.

Usage and Lifespan of Plastic Household Items Molds

The usage and lifespan of household plastic molds depend on several interacting factors, including material choice, operating conditions, and maintenance practices. Proper usage can significantly extend mold service life and maintain consistent product quality.

◆ Typical Usage Scenarios

Household plastic molds are used in injection molding machines operating under controlled temperature and pressure conditions. They may run continuously in large factories or intermittently in smaller production settings. Stable process parameters reduce mechanical stress on mold components.

◆ Expected Lifespan Range

The lifespan of a household plastic mold is often measured in the number of molding cycles. For example:

※ Aluminum molds: approximately 50,000–200,000 cycles

※ P20 steel molds: approximately 300,000–600,000 cycles

※ Hardened steel molds: up to or beyond 1,000,000 cycles

These figures are approximate and can vary depending on plastic type and mold complexity.

◆ Maintenance and Care Factors

Regular cleaning, lubrication, and inspection are essential. Removing plastic residue, checking cooling channels, and monitoring wear on ejector pins help prevent unexpected downtime. Scheduled maintenance reduces the risk of surface damage that could affect product appearance.

◆ End-of-Life Considerations

When molds reach the end of their service life, they may still be refurbished through re-polishing or component replacement. In some cases, retired molds are repurposed for low-precision products, extending their practical value.
