Stool Mould
A stool mold refers to a specialized tool or die used in the manufacturing process to produce plastic stools. It is a precision-made mold designed to shape and form molten plastic material into a specific stool design. These molds are crucial components in the injection molding or blow molding processes used to create plastic stools.
Benefits of Stool Mould
Fast and efficient
One of the key advantages of stool mould is its ability to produce high volumes of plastic stools quickly and efficiently. The process is highly automated, allowing for continuous production with minimal downtime. This makes stool mould ideal for mass production, where large quantities of identical products are required.
High temperature performance
When the working temperature of the mold is high, the hardness and strength will decrease, leading to early wear or plastic deformation failure of the mold. Injection mold processing materials should have high tempering resistance to ensure that the mold has high hardness and strength at working temperature.

The Manufacturing Process of Stool Mould Involves Several Steps
Design and Planning
The process begins with a thorough understanding of the stool design requirements. Engineers and designers create detailed 3D CAD (computer-aided design) models based on specified stool dimensions and features.
Material selection
Select appropriate mold manufacturing materials based on design specifications. Common materials include high-grade steel, aluminum alloys, or composites known for their durability and strength.
Machining and molding
Machining processes such as milling, turning, grinding and electrical discharge machining (EDM) are used to form mold parts. CNC (computer numerical control) machines are often used to achieve precise and complex mold designs.
Heat Treatment
Some molds undergo a heat treatment process to increase their hardness, durability, and wear resistance. Heat treatments such as tempering or hardening are used to improve material properties.
Assembly and Finishing
The mold parts are carefully assembled and assembled. Skilled technicians ensure proper alignment and accuracy during assembly. Surface finishing such as polishing or coating can be applied to achieve a desired texture or appearance.
Quality Control and Testing
Strict quality checks and inspections are conducted at all stages of mold manufacturing. This includes dimensional inspections, surface quality assessments and functional testing to ensure molds meet design specifications and quality standards.
Trial run and adjustments
Once the mold is assembled, a trial run is performed using test materials to produce fecal samples. Adjustments and fine-tuning are made to ensure the mold produces a high-quality stool that meets the expected specifications.
Deployment and Production
After successful testing and validation, the plastic stool mold is ready for deployment in the manufacturing process. Molten plastic material is injected or blown into a mold cavity under controlled conditions to produce a plastic stool.
Maintenance and life management
Develop a regular maintenance schedule to ensure longevity and optimal performance of your molds. Maintenance activities include cleaning, lubrication, repairs and regular inspections to prevent wear and extend the life of the mold.
How to Check the Quality of Stool Mould
Visual Inspection
Visually inspect the mold surface for any obvious damage, wear or irregularities. Check for cracks, dents, or signs of corrosion that may affect mold performance.
Dimensional Inspection
Use precision measurement tools such as calipers, gauges, or rulers to inspect critical dimensions of mold parts. Verify mold dimensions meet specified design requirements.
Surface quality assessment
Check the surface finish of the mold. A smooth and even surface is crucial to producing high-quality plastic stools. Look for any flaws or irregularities that may affect the appearance of the final product.
Functional testing
Functional testing is performed to ensure that all moving parts, slides, and mechanisms within the mold operate smoothly and correctly. Check the ejection system, locking mechanism and cooling channels to ensure proper function.
Mold Alignment
Verify that all mold parts are properly aligned during assembly. Misalignment can cause defects in the molded stool. Check for any signs of misalignment or gaps between mold parts.
Material Flow Analysis
Conduct material flow analysis to ensure proper distribution of molten plastic within the mold cavity. Look for potential flow restrictions or uneven filling areas that could cause molding defects.
Wear Assessment
Evaluate the wear of mold components, especially areas that experience high stress during the molding process. Check critical areas for signs of wear, corrosion or fatigue that could affect mold life
Cleaning and Maintenance
Make sure the mold is clean and free of any residue or contaminants that could affect the molding process. Follow a regular maintenance schedule to prevent mold parts from building up, corrosion, or damage.
Processing Details of Stool Mould
The processing of plastic stool mold is mainly core and cavity. The processing of the cavity of the stool mold mainly depends on whether the CNC processing tool is long enough to process without shaking the tool. Some stool designs are difficult to process in place at one time, so EDM is also needed.
After finishing CNC and EDM, the cavity of the stool mold also needs to arrange deep hole drilling to process the waterway as well as polishing. The processing of the core of the stool mold can be completed by the conventional CNC processing.
For more accurate processing, we will use five-axis high-speed milling with 20,000r/min to process the parting surface of the stool mold in place at one time to avoid secondary processing. After finishing the shape processing, the back of the core of the stool mold also needs to process the ejector hole, we usually put it on the five-axis deep hole drill to process, usually the processing time of the ejector hole of a stool mold is 18 hours.
Different Types of Stool Molds
Injection mold
Injection molds are used to produce plastic stools with complex shapes and intricate details. This type of mold is made by injecting molten plastic into a cooled mold, which then cools and solidifies. Injection molds are highly precise and can produce stools with high consistency and precision. They are also able to produce stools in large quantities, making them a popular choice for mass production.
Compression mold
Compression molds are used to create plastic stools with simpler designs and fewer details. This type of mold is made by placing a preheated plastic sheet between two cooled mold halves and applying pressure to form the plastic into the desired shape. Compression molds are generally cheaper and faster to produce than injection molds, making them a good choice for small production or for producing basic stools.
Blow mold
Blow molds are used to make hollow plastic stools, such as those with cutout designs or those that are lightweight and portable. This type of mold is created by injecting molten plastic into a cooled mold and then using pressurized air to blow the plastic into the desired shape. Blow molds are often used to create stools with unique designs and are not suitable for mass production.
Proper use: Before using the stool mould, it is necessary to check the condition of the Mould to ensure that there is no obvious damage or wear. When using, it is necessary to operate according to the instructions to avoid damage to the mould caused by excessive force or improper use.
Regular cleaning: After using the stool mould, it needs to be cleaned and maintained regularly to ensure its normal work and prolong its life. When cleaning, you can use detergent and soft cloth to clean, and be careful not to use brushes or other hard objects to scratch the surface of the Mould.
Protects against oxidation: Stool moulds are usually made of metal and are susceptible to oxidation. In order to prolong the service life of the Mould, you can apply a layer of protective oil or antirust agent after cleaning to avoid oxidation.
Proper storage: After using the stool mould, it needs to be properly stored in a dry and ventilated place to avoid being affected by humidity and high temperature. A layer of protective oil or anti-rust agent can be applied to protect the Mould during storage.
Regular Inspections: Check the condition of the Stool Mould regularly, especially before use, to ensure there is no visible damage or wear. If a problem is found, it should be repaired or replaced in time.
