Rotational molding furniture mold

How to ensure the rationality of roto-molding furniture mold design to avoid quality problems during the molding process?

At Jiangsu Zhuohe Company, we are well aware that the rationality of roto-molding furniture mold design is crucial to avoiding quality problems during the molding process. In order to ensure the scientificity and efficiency of mold design, we have taken a series of rigorous and meticulous measures, relying on our technical strength and equipment advantages, which are specifically reflected in the following aspects:
High-precision design and simulation: We use advanced CAD/CAM design software, combined with years of accumulated experience in roto-molding mold design, to perform precise three-dimensional modeling and simulation. This process not only considers the appearance and functional requirements of the product, but also deeply analyzes key factors such as material flow, cooling effect and stress distribution to ensure that the mold design is theoretically optimal, thereby avoiding deformation, cracks and other quality problems during the molding process.
Strict dimensional accuracy and standardization management: Jiangsu Zhuohe Company implements strict inspection processes and time control for every size of the mold to ensure the standardization and high precision of all parts. This includes strict screening of raw material hardness, fine control of the processing process, and precise operation of CNC machining centers, especially the use of high-speed five-axis gantry machining centers for rough machining, semi-finishing and finishing of molds, which greatly improves the accuracy and consistency of molds and reduces molding problems caused by dimensional deviations.
Material flow inspection and wall thickness control: We are well aware of the impact of material flow on molding quality in the rotational molding process, so we pay special attention to the inspection and optimization of material flow. By accurately controlling the heating temperature, rotation speed and cooling time of the mold, we ensure that the material flows evenly in the mold to avoid defects such as bubbles and shrinkage holes. At the same time, using the unique wall thickness control ability of the rotational molding process, we ensure that the edge thickness of the furniture mold exceeds 5mm, significantly improving the edge strength and meeting the high requirements for durability and safety of outdoor furniture, children's furniture, etc.
Professional straightening, assembly and polishing: After the mold is manufactured, we strictly follow customer requirements to finely straighten and assemble the CNC-processed mold core and frame to ensure the accuracy and stability of the mold. Subsequently, professional mechanical polishing is carried out to create a deep and evenly distributed texture pattern, which not only improves the beauty of the product, but also further optimizes the quality of the molding surface.
Continuous technological innovation and customer communication: We continue to invest in research and development, introduce new technologies and new materials, and improve the level of mold design and manufacturing. At the same time, we maintain close communication with customers, deeply understand their specific needs and expectations, and ensure that the mold design meets both technical requirements and customer's personalized needs, thereby avoiding quality problems in the molding process from the source.
Jiangsu Zhuohe Company relies on high-precision design and simulation, strict dimensional accuracy and standardization management, material flow inspection and wall thickness control, professional straightening assembly and polishing, as well as continuous technological innovation and customer communication to ensure the rationality of rotomolding furniture mold design, effectively avoid quality problems in the molding process, and provide customers with top plastic furniture solutions.

How to control the cooling rate and cooling medium to ensure the quality of rotomolding furniture molds during the cooling stage?

At Jiangsu Zhuohe Company, we are well aware that quality control of rotomolding furniture molds during the cooling stage is crucial to the durability, dimensional accuracy and appearance of the final product. Therefore, we have adopted a series of precise and efficient methods to control the cooling rate and select the appropriate cooling medium to ensure that the quality of rotomolding furniture molds reaches the top level.
Cooling rate control
Intelligent temperature control system: We have introduced an advanced intelligent temperature control system that can automatically adjust the cooling rate according to the mold size, material properties and preset process parameters. By accurately monitoring the temperature changes inside the mold, the system can ensure that the cooling process is uniform and stable, avoiding stress concentration and deformation problems caused by too fast or too slow cooling.
Phased cooling strategy: For molds of different parts and thicknesses, we implement a phased cooling strategy. A faster cooling rate is used in the initial stage to quickly take away a lot of heat, and then the cooling rate is gradually slowed down to promote uniform shrinkage of the material and release of internal stress, thereby improving the overall quality of the mold.
Cooling medium selection
High-quality cooling medium: We strictly screen and use high-quality cooling medium, such as pure water or coolant with a specific ratio, to ensure that it has good thermal conductivity, chemical stability and low corrosiveness. These characteristics help achieve efficient heat exchange while protecting the mold surface from damage.
Circulating cooling system: Equipped with an advanced circulating cooling system, it ensures that the cooling medium circulates continuously around the mold to maintain a constant temperature and flow rate. This not only improves cooling efficiency, but also helps reduce medium waste and environmental pollution.
Zhuohe Company's unique advantages
