Description

Technical Field

[0001] The present invention relates to the technical field of injection molding for cans, and particularly to a can-making machine equipped with a titanium-plated mold and its processing technology. Background Art

[0002] During the production process of existing can-making machines, in order to smoothly demold the can body, it is usually necessary to apply a release agent on the surface of the mold; for example, a multi-station can-making machine with the patent publication number CN102773327B. This step not only increases the complexity of the operation but also poses higher requirements for the can-making materials; on the one hand, the can-making materials need to have good compatibility with the release agent to ensure that the release agent can adhere evenly and does not damage the surface of the materials; on the other hand, the materials themselves need to have a certain degree of oil resistance and chemical stability to prevent deterioration or performance degradation during long-term contact with the release agent, thus affecting the quality of the can body and production efficiency.

[0003] In can-making processing, oiling for demolding is an essential step, but this step has many drawbacks; first of all, the oiling process requires precise control of the oil application amount and uniformity, otherwise it is easy to cause uneven oil films on the surface of the can body, affecting the demolding effect and the appearance quality of the can body; for example, a forming mold device for can-making processing with the patent publication number CN118832062A. This requires that the can-making materials have a certain tolerance to oil stains and can still maintain good formability under slight oil stain conditions; secondly, the selection of release agents is limited and needs to take into account the material characteristics. It is necessary to ensure smooth demolding and not cause adverse reactions with the materials, further restricting the selection range of materials and making the screening and requirements for can-making materials more stringent.

[0004] In traditional can-making processes, the step of oiling for demolding is extremely cumbersome; in order to effectively adhere the release agent, it is necessary to pre-treat the mold and materials, such as cleaning, drying, etc., increasing the process and time costs; at the same time, the can-making materials need to adapt to this process of multiple treatments and have good weather resistance and stability to avoid problems such as deformation and wear during repeated cleaning and oiling; moreover, to meet environmental protection and product quality requirements, the materials also need to match the selected release agent to ensure that under complex working conditions such as high temperature, they can be smoothly demolded without generating harmful substances or residues, such as the high-temperature heat-resistant oily release agent, high-temperature heat-resistant electrostatic coating type oily release agent and its coating method with the patent publication number CN106132586A. This undoubtedly greatly improves the requirements for the performance and quality standards of can-making materials; for this reason, a can-making machine equipped with a titanium-plated mold and its processing technology are provided to solve the above problems.
