What are the main types of China mould parts and how to choose them?

China mould parts are components that are used to make moulds for various industries, such as plastic, metal, ceramic, glass, etc. Moulds are tools that shape materials into desired forms by applying heat, pressure, or both. China mould parts can be classified into four main types: core, cavity, runner, and gate.

Core: The core is the part of the mould that forms the inner surface of the product. It is usually made of steel or alloy and has a high hardness and wear resistance. The core should match the shape and size of the product and have a smooth surface to facilitate demoulding.

Cavity: The cavity is the part of the mould that forms the outer surface of the product. It is also usually made of steel or alloy and has a high hardness and wear resistance. The cavity should match the shape and size of the product and have a smooth surface to facilitate demoulding.

Runner: The runner is the part of the mould that connects the injection nozzle and the gate. It is a channel that transports the molten material from the injection machine to the mould cavity. The runner should have a proper diameter and length to ensure a uniform flow rate and pressure of the material.

Gate: The gate is the part of the mould that controls the entry and exit of the material into and out of the mould cavity. It is a small opening that connects the runner and the cavity. The gate should have a proper size and location to ensure a complete filling and cooling of the material.

To choose China mould parts, one should consider several factors, such as:

• The type and properties of the material to be moulded
• The shape and size of the product to be produced
• The production volume and cycle time
• The quality requirements and standards
• The cost and availability of the parts

By comparing different types and brands of China mould parts, one can select the most suitable ones for their specific needs.

How to inspect and test China mould parts before shipment?

China mould parts are widely used in various industries, such as automotive, medical, electronics, and so on. However, before shipping these parts to customers, it is essential to inspect and test them for quality and performance. This article will introduce some common methods and procedures for inspecting and testing China mould parts before shipment.

The first step is to check the appearance of the mould parts. This includes checking for any defects, such as cracks, scratches, burrs, deformation, discoloration, etc. The appearance of the mould parts should match the specifications and drawings provided by the customer. Any deviation or discrepancy should be reported and corrected immediately.

The second step is to measure the dimensions of the mould parts. This includes measuring the length, width, height, diameter, thickness, angle, radius, etc. of the mould parts using appropriate tools and instruments, such as calipers, micrometers, gauges, etc. The dimensions of the mould parts should be within the tolerance range specified by the customer. Any deviation or discrepancy should be reported and corrected immediately.

The third step is to test the functionality of the mould parts. This includes testing the mechanical properties, such as hardness, tensile strength, impact resistance, etc. of the mould parts using appropriate equipment and methods, such as Rockwell hardness tester, universal testing machine, impact tester, etc. The functionality of the mould parts should meet the requirements and standards specified by the customer. Any deviation or discrepancy should be reported and corrected immediately.

The fourth step is to test the compatibility of the mould parts with other components or materials. This includes testing the fit, assembly, sealing, bonding, etc. of the mould parts with other components or materials using appropriate techniques and procedures, such as trial assembly, leak test, adhesion test, etc. The compatibility of the mould parts should ensure the smooth operation and performance of the final product. Any deviation or discrepancy should be reported and corrected immediately.

The fifth step is to verify the compliance of the mould parts with relevant regulations and certifications. This includes verifying the safety, environmental protection, quality management, etc. of the mould parts using appropriate documents and certificates, such as ISO 9001 certificate, CE certificate, RoHS certificate, etc. The compliance of the mould parts should meet the expectations and demands of the customer and the market. Any deviation or discrepancy should be reported and corrected immediately.

By following these steps, China mould parts can be inspected and tested before shipment to ensure their quality and performance. This will not only satisfy the customer’s needs and expectations but also enhance the reputation and competitiveness of China mould manufacturers in the global market.

How to maintain and store China mould parts properly?

• China mould parts are essential components of various industrial and manufacturing processes. They are used to create precise shapes and forms of plastic, metal, rubber and other materials. However, China mould parts can also be subject to wear and tear, corrosion, deformation and damage if they are not maintained and stored properly. Therefore, it is important to follow some basic guidelines to ensure the longevity and quality of China mould parts.
• The first step is to clean the China mould parts after each use. This can prevent the accumulation of dust, dirt, grease, oil and other contaminants that can affect the performance and appearance of the mould parts. Cleaning can be done by using a soft cloth, a brush or a compressed air gun to remove any loose particles. Then, a mild detergent or a solvent can be applied to wipe off any stains or residues. Finally, the China mould parts should be rinsed with water and dried thoroughly.
• The second step is to inspect the China mould parts for any signs of damage or wear. This can help to identify any cracks, chips, scratches, dents or rust that can compromise the integrity and functionality of the mould parts. If any damage or wear is found, the China mould parts should be repaired or replaced as soon as possible. Repairing can be done by using a filler material, a welding machine or a grinding tool to restore the original shape and surface of the mould parts. Replacing can be done by ordering new China mould parts from a reliable supplier.
• The third step is to lubricate the China mould parts regularly. This can reduce the friction and heat that can cause the mould parts to wear out faster. Lubricating can also prevent the mould parts from sticking together or to the moulding machine. Lubricating can be done by using a spray, a grease or a oil that is suitable for the type and material of the China mould parts. The lubricant should be applied evenly and sparingly to avoid excess buildup or leakage.
• The fourth step is to store the China mould parts properly when they are not in use. This can protect them from moisture, dust, sunlight and extreme temperatures that can cause corrosion, deformation or deterioration of the mould parts. Storing can be done by placing the China mould parts in a dry, cool and dark place. They should also be wrapped in plastic bags or covered with cloth to prevent dust and dirt from settling on them. Moreover, they should be arranged in an orderly manner to avoid scratching or denting each other.
• By following these four steps, China mould parts can be maintained and stored properly for a long time. This can ensure their optimal performance and quality in various industrial and manufacturing processes.
