Injection molding is a method commonly used in plastic processing. This method is applicable to all thermoplastics and some thermosets.
What does Medical Mold's production include?
What are the characteristics of Medical Mold?
How to restore the injection mold after deformation?
①Disposable medical plastic appliances, such as disposable plastic infusion sets, syringes, blood vessels, extension tubes, connecting tube drainage bags, etc.
②Plastic human organs for surgery, extracorporeal circulation access catheters, laryngeal masks, artificial kidneys, artificial lungs, artificial joints, etc.
③Medical plastic parts, such as tracheal intubation, airway, intravascular intubation, puncture cannula, and various medical plastic products for repair, nursing, physiotherapy and diagnosis.
④Medical plastic packaging materials, eye drop bottles, oral liquid bottles, polyvinyl chloride plastic bottles, low density polyethylene ointment tubes, etc.
⑤Medical plastic product containers, including various plastic bedpans, washing basins, packaging bags, etc.
⑥Clinical plastic products and consumables, including disposable medical test tubes, centrifuge tubes, Petri dish measuring cups, etc.
First of all, in the production process of injection molded products, the temperature of injection molding Medical Mold is generally high.
Therefore, the injection mold steel produced by the injection mold factory must be the mold steel that has been tempered at high temperature, so that even in a high temperature environment, the overall designed mold size will not be affected, thus ensuring the overall accuracy of the mold.
Secondly, in the process of injection molding, the raw materials of plastic products such as resin and various additives will corrode the surface of the injection-molded Medical Mold and affect the overall accuracy of the injection-molded Medical Mold. Therefore, corrosion-resistant steel must be used when selecting mold steel.
In the process of injection mold and product production, various defects and deformations often occur in mold materials: one of the reasons for material deformation is to reduce costs, the actual use of mold materials is not special mold steel, template rigidity, insufficient thickness, improper heat treatment, residual stress, EDM stress, etc., the above reasons often interact to increase the amount of deformation.
In addition to the corresponding solutions, widen the die feet or use a force post in the middle of the die.
Some molds themselves are not very demanding, and can be heated and deformed at a high temperature immediately at the focus position, which is quite effective.
People often grind off the edges of the template to reduce the contact surface and minimize the depth of grinding to promote the effective life of the mold.
The cavity size deviation after the template is deformed is difficult to correct, the core is too tight, the cavity wall is deformed, the multi-cavity phenomenon is particularly serious, and the flash in the middle of the template will not change, especially when injecting products with good fluidity such as nylon, The weight core should be ground flat. When the template is deformed, the amount of deformation cannot be ignored.
With over 16 years history, SMARTELL TECHNOLOGY CO., LTD. has became professional in the production and development of syringes and infusion set production molds, machines and other necessary equipment.
