Qingdao Zhenxiong Mechanical Equipment Co., Ltd.The length of the cooling water tank is not simply a pursuit of "numerical maximization", but a scientific balance based on material properties and quality stability.1. 8-meter waterwayThe internal heat of the high-temperature adhesive strip needs to be deeply transferred, and a short water tank can cause "cold skin and hot core", burying hidden deformation hazards; Double stage circulating water spray cooling water tank, with a total length of 8 meters in two sections, provides sufficient cooling path and time for the cooling and shaping of the door seal, eliminates residual stress, and ensures that the door seal is not easily deformed.2. Spray cooling, uniform shapingCirculating water evenly wraps around the high-temperature extruded door seal through dense spray holes, avoiding local rapid cooling and allowing the material to cool and solidify smoothly and synchronously from the surface to the inside.Not all cooling is called 'sufficient cooling'. Qingdao Zhenxiong Mechanical - Refrigerator Door Seal Production Line, with an 8-meter dual segment spray system, uses scientific space allocation and water flow control to ensure product size stability from the source and long-term use without deformation.

Good processability: easy to melt and plasticize, moderate fluidity, high extrusion molding efficiency, smooth surface.Strong sealing: The product is soft and elastic, and can tightly fit the refrigerator door, providing good sealing and insulation effects.Anti aging: good weather resistance, not easy to harden, crack or discolor after long-term use.Good low-temperature toughness: It maintains good flexibility and sealing performance even in low-temperature environments of refrigerators.Easy to bond/weld: The particles have good bonding performance after melting, making it easy to weld the end of the door seal or bond with other components.High stability: The formula is stable, not easily decomposed during processing, and the product size stability is good.High cost-effectiveness: Providing good cost-effectiveness while meeting performance requirements.

The fully automated refrigerator door seal production line adopts a PLC intelligent control system to coordinate the orderly production of each link. The entire line can operate efficiently with only one person:1. Configure an automatic drying and feeding machine with automatic overload and shortage alarms to reduce labor costs;2. Spray cooling+water removal device solves the deformation/water mark problem caused by traditional water tank cooling;3. Automatic drilling device: automatically completes precise hole position processing to ensure position consistency;4. The traction speed is controlled by a frequency converter, equipped with a pneumatic cutting device, and the cutting length and size can be adjusted;5. 45 fully automatic cutting machine, capable of cutting both ends of the rubber strip into a 45 degree angle with a cutting accuracy of ± 1mm;6. The robotic arm is controlled by photoelectric technology to automatically clamp and smoothly place the adhesive strip onto the receiving table.This type of fully automatic refrigerator door seal production line can stably support long-term continuous operation, helping enterprises reduce labor costs while increasing production capacity, especially suitable for large-scale order production scenarios.

Raw material selectionThe raw materials for magnetic strips must comply with relevant standards to ensure good magnetic properties, stable magnetism, wear resistance, and long service life.Device SelectionOur company's independently developed and produced magnetic strip extrusion production line, also known as automated and efficient production, has a high output and can be used for the production of magnetic strips for various door seals such as refrigerators, freezers, and bathrooms. The magnetic strips produced have strong magnetic force, high quality, wear resistance, and long service life.Strict temperature controlStrictly control the temperature to ensure normal production.Storage and transportationAvoid squeezing or collisionThe storage environment should be kept dry and avoid moistureMagnetic Flux Leakage TestingThe magnetic strip extrusion production line is equipped with a magnetic leakage detection device, which automatically alarms for magnetic leakage.

The fully automatic welding machine for door seals is a specialized equipment used for welding door seals of household appliances such as refrigerators and freezers. Its core value lies in improving the automation level of welding processes, ensuring product consistency and reliability.The fully automatic welding machine is used for welding sealing strips at a 90 ° angle, and adopts a PLC automatic control system with high welding accuracy. The mold and tooling are divided into upper and lower layers, which can weld double corners simultaneously, doubling the production capacity. The equipment has an automatic cleaning function for weld beads, which helps to save labor costs.In terms of operational safety, a photoelectric protector is installed in front of the mold, and the equipment uses a dual hand start button and is equipped with an HZ12-25 cut-off switch to prevent electric shock. The equipment mainly uses branded electrical components, which provides guarantees for its operational stability and low failure rate.The production capacity of this equipment can reach 600-650 sets/shift, with high welding efficiency. The welding area has sufficient strength, the product can withstand high pressure, and is not easily deformed, ultimately ensuring that the welding angle is flat, firm, and aesthetically pleasing.It is suitable for batch welding of door seals for refrigerators, freezers, disinfection cabinets, water dispensers, and other devices. The welding effect is smooth and can automatically remove weld beads, thereby saving labor.

The production of door seal molds follows a rigorous process route to ensure their processing accuracy and service life. The core process is as follows:1, Drawing design and material preparation(1) Design based on the drawings or physical samples provided by the customer. If there are no drawings, a door seal projector can be used for precise surveying.(2)The mold material is made of 40Cr mold steel, which is quenched, tempered and forged to improve the strength, wear resistance and impact resistance of the mold, ensuring the machining accuracy of the mold.2, Core precision machining(1)Grinding machine processing: Ensure the flatness and dimensional accuracy of the mold substrate.(2) Wire cutting: Processing to form the core contour and cavity of the mold.(3)Drilling hole(4)Milling edge(5)Electroplating and polishing treatment: to reduce surface roughness and improve demolding effect.(6)Blow needle cooling(7)After the mold assembly is completed, laser marking is carried out for easy identification and differentiation.3: Trial molding and factory inspectionAfter the mold assembly, a trial mold is required to verify its actual molding effect.The trial sample can only be arranged for shipment after passing the inspection.

Mould is composed of welding mould, guiding mould and ejecting mould. Installing method: (1) Keep edges align of left mould and right mould and install firmly. (2) Keep guiding mould align; insert gasket fluently and the screw tightly. (3) Ejecting mould is installed firmly, ejecting and reset fluently, no stagnancy. (4) Keep the mould cover tightly, open and clamp mould should be no loose. (5) Forbid operate this equipment before installing the mould.
