Medical product mold manufacturers: common appearance problems of medical device parts and injection molds
Medical product mold manufacturers talk about the appearance characteristics of medical device parts. In the medical device parts industry, the appearance quality of products is very high, but it is characterized by a small number of varieties, so the manufacturer's process capability management requirements are very high. The appearance of the product customers want is the more perfect the better, no defects, medical product mold manufacturers want the appearance requirements of the lower the better, so how to balance the product appearance quality standards, and how to fully and effectively land, improve product yield, medical product mold manufacturers will carry out the following analysis.

Medical product mold manufacturers: the particularity of the appearance problem situation
Depending on the decision, different conclusions can be drawn for the same idle. The evaluation results may be different, that is, different customers have different requirements for appearance.
The judgment of appearance defects is different from performance and function, and has its special side. The relationship between ideal standard, actual control and customer requirements can be used to illustrate the judgment of appearance defects. Ideal standard: The judge believes that his standard meets the customer's requirements. Actual control means that the judge determines the physical object. Customer requirements represent the extent to which defects are allowed for each particular customer. There are many ways to know. These three have the following relationship:
The ideal standard is higher than the customer's demand, but the actual control is more and more strict. At this time, a large number of good products are scrapped as defective products, and there may be excessive quality requirements.
The ideal standard is higher than the customer's requirements, but the actual control is more and more loose, gradually lower than the customer's demand, the product appearance is not good for the customer, the appearance of dissatisfaction increases, the company's reputation is damaged.
Medical product mold manufacturers to share the general solution of the shape problem
The appearance sample is easy to set, but how to know that the sample is close to the customer's requirements? How to know that the actual control is slightly higher than the customer's requirements? How to avoid the blind spot in the penalty? The following methods are worth trying.
Medical product mold manufacturers believe that they should communicate with the demanders.
For defects that are difficult to determine (defective or good products), the contents of the defect can be recorded, the rationality of the standard can be discussed together, the quality standards that cannot be clearly defined before development can be collected, the types of defective products, the proportion of defective products and statistical data of each batch in the factory can be verified, and then the reasonable standards consistent with the requirements can be confirmed according to the actual data.
Regular visits to those in need.
Product quality engineers regularly visit demanders, timely communication, define reasonable standards.
Establish appearance baselines.
For controversial appearance defects, set the same sample in advance, find the sample for comparison, you can clearly determine. Only by establishing the appearance standard of mutual trust, statistical analysis of the judgment of appearance defects, and tracking reasonable definitions, can we reduce "mishandling", reduce unnecessary costs due to excess quality, reduce market dissatisfaction, and maintain market credit.
Summary of medical product mold manufacturers: The definition and implementation of appearance quality standards must first follow the principle of continuous and stable mass production, and secondly, strict adverse phenomena and statistical analysis must be carried out before mass production of products, and reasonable standards must be defined according to actual statistical analysis results. Finally, the root of all quality problems cannot be separated from people, machines, materials, laws, and links to do a good job in product quality.
