Introduction
In the manufacturing industry, choosing the right mould factory for cooperation is of utmost importance. The quality of moulds directly impacts the quality of the final products, production efficiency, and overall costs. A sub - optimal choice can lead to defective products, production delays, and increased expenses. This article will explore from multiple aspects such as product quality, production capacity, cost - effectiveness, and after - sales service to help you figure out which kind of mould factory is better for cooperation. By the end, you'll be equipped with the knowledge to make an informed decision and build a successful partnership in the mould - making field.
Production Capacity
Equipment and Technology
Advanced equipment is the cornerstone of high - production - capacity mould factories. High - precision machining centers can achieve extremely accurate milling, drilling, and boring operations. For example, a five - axis machining center can process complex three - dimensional mould shapes with high precision. It allows the workpiece to be machined from multiple angles without re - clamping, reducing errors and improving production efficiency. The positioning accuracy of high - end machining centers can reach up to ±0.001mm, which is crucial for manufacturing moulds with tight tolerances.
CNC electrical discharge machining (EDM) machines are also essential. They use electrical discharges to erode the workpiece and create intricate shapes that are difficult to machine by traditional methods. In a precision mould production for a high - end electronic product, an EDM machine can create micro - structures with a minimum feature size of 0.01mm. Factories equipped with such advanced EDM machines can handle complex mould designs more efficiently, which significantly boosts production capacity and product quality.
Production Scale
The production scale of a mould factory directly affects its order - handling ability and production cycle. The following table shows the differences between large - scale and small - scale mould factories:
| Factory Scale | Monthly Production Capacity (Sets) | Average Order - Handling Capacity per Month | Average Production Cycle for a Medium - Sized Mould Order |
| Large - scale | 500 - 1000 | 30 - 50 | 2 - 3 months |
| Small - scale | 50 - 150 | 5 - 10 | 4 - 6 months |
Large - scale mould factories usually have more production lines, a larger number of workers, and better - organized production management systems. They can handle large - volume orders from major automotive or electronics manufacturers. In contrast, small - scale mould factories are more suitable for small - batch, customized orders due to their limited resources and production capacity.
Product Quality
Quality Control System
A sound quality control system is the bedrock of a high - quality mould factory. It typically encompasses raw material inspection, in - production process monitoring, and finished - product testing.
Take a mould factory that has obtained ISO 9001 certification as an example. Before production starts, they conduct strict raw material inspections. They use spectrometers to analyze the chemical composition of metal materials to ensure they meet the required standards. For example, if the mould is made of a specific alloy steel, the spectrometer can accurately measure the content of elements like carbon, chromium, and nickel, guaranteeing that the raw materials have the correct properties for the intended mould application.
During the production process, real - time monitoring is carried out. Sensors are installed on machining equipment to monitor parameters such as temperature, vibration, and cutting force. Abnormalities in these parameters may indicate tool wear, incorrect machining operations, or other issues that could affect the quality of the mould. For instance, if the temperature of a milling machine spindle rises abnormally, it might lead to thermal expansion of the cutting tools, resulting in dimensional inaccuracies in the mould parts.
Once the mould is completed, comprehensive finished - product testing is performed. Coordinate measuring machines (CMMs) are used to measure the dimensions of the mould with high precision. A CMM can measure complex three - dimensional shapes with an accuracy of up to ±0.001mm, ensuring that all the features of the mould meet the design requirements.
Material Selection
The choice of raw materials has a profound impact on mould quality. Different materials can lead to significant differences in mould durability and accuracy retention.
For example, in the production of injection moulds, using high - quality P20 steel compared to lower - grade steels can make a big difference. P20 steel has good machinability, hardness, and toughness. Moulds made of P20 steel can maintain their dimensional accuracy during long - term production runs. They can produce hundreds of thousands of injection - molded products with consistent quality. In contrast, lower - grade steels may experience more rapid wear and deformation during the injection - molding process. This can result in the production of defective products, as the mould cavity may gradually lose its original shape, leading to issues such as inconsistent wall thickness and surface defects in the molded parts.
Another example is in the manufacturing of die - casting moulds. Hot - work die steels like H13 are preferred due to their excellent heat resistance, high temperature strength, and thermal fatigue resistance. Die - casting moulds made of H13 steel can withstand the high - temperature and high - pressure environment during die - casting operations for a long time. They can produce high - quality die - cast parts with complex shapes. If an inappropriate material is used, the mould may crack or deform quickly under the harsh die - casting conditions, reducing the production efficiency and increasing the cost of mould replacement.
