Quality Door Gasket Production Line & Refrigerator Magnetic Strip factory

Recently, our company's customized refrigerator door seal production line for customers has successfully completed all assembly work, and the entire line is now ready.The production line is strictly manufactured according to customer technical requirements and standards, and is currently in the final preparation stage before delivery. All will undergo multiple processes of inspection, strictly following quality inspection standards for inspection, debugging, and loading to ensure batch delivery quality and meet customer equipment requirements.After passing the trial run, the production line will immediately pack and arrange for shipment.

Our company has successfully completed the production and commissioning of 20 high-performance extruders tailored for customers, and officially loaded and shipped them.This batch of equipment is deeply customized according to the customer's production process and requirements, ensuring a perfect fit between the equipment and the production line. During the production process, we strictly control the quality checkpoints to ensure that every device meets the high standard delivery requirements.With the smooth departure of this batch of equipment, they will soon be put into production and operation for customers. We look forward to these devices creating outstanding value for our customers and wish both parties fruitful cooperation!

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.

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.

The advantage of non-standard automation is the flexibility of solution design. We can provide customized solutions and comprehensive technical support according to different needs. requirement analysis Product related requirements Customized requirements Cost budget for equipment Other precautions, etc Develop a  plan The plan meets the customer's needs: Fully consider various factors, analyze and formulate equipment solutions. Scheme review Technical team evaluation: Assess the feasibility of all aspects of the equipment. Plan rectification: Rectify the problems discussed in the scheme. Customer confirms plan According to the customer's needs, the plan is finalized. Manufacture Strictly follow the quality standards, Ensure the accuracy and stability of the equipment. Installation and Debugging Strictly assemble equipment according to standards Test and debug the equipment The equipment has been packaged and shipped After-sales service Provide long-term after-sales service support for customers

Recently, our technicians went overseas to the customer's factory to provide after-sales commissioning services for PVC Plastic Door Doard Making Machine Extrusion Line and Wood Plastic Profile Production Line. After two weeks of intensive debugging, all indicators of the equipment have reached or exceeded the customer's expected standards, and have received high praise from the customer. This cross-border technical support not only deepens the cooperation relationship with customers, but also establishes a good brand image for the company in overseas markets. For over 20 years, we have actively expanded our overseas markets and exported our products to multiple countries and regions around the world. In order to better serve overseas customers, the company has established a comprehensive after-sales service system and cultivated an experienced and technically proficient after-sales service team that can quickly respond to customer needs and provide timely, efficient, and convenient services.
