New natural rubber products in the production before must first open mold, and open mold is divided into sample mold and open large mold two kinds.

Many customers who can not make silica gel products often ask a question, that is: "Silica gel products have a production mold, why should we open the sample mold?" , why waste time and energy to open another set of sample mold? But for the sample mold, it is a very important link before production, the following to take you to understand.

Analyze the significance of opening the test mold from two angles:

1. The customer

When the customer develops and designs a new silicone product, there are still some unknowns about the new product, such as uncertain performance and whether the structure meets the expected effect. At this time, it is necessary to open the test mold first, with the test mold proofing, rather than directly open the large mold, which can not only solve the customer's requirements for the sample of the silica gel products, but also save the cost of customers.

2. Silica gel manufacturers

Opening the test mold first can reduce the mold opening risk of silica gel mold. Occasional mold repair may have little impact on the mold, but too much mold repair will affect the subsequent production of the mold, because the more mold repair, the worse the mold itself. If the sample mold is first opened to determine the size and structure of the product, then in the formal mass production, it is only necessary to directly cover the mass production mold according to the design of the sample mold and open it once, so that the number of modifications of the mass production mold can be effectively reduced, and the quality of the subsequent production of silica gel products can be stable.

Sometimes when the size and structure of the silica gel products sent by customers are not very accurate or completely determined, we usually use the sample mold to develop, which will be very convenient to modify the size and structure of the silica gel products in the later period. And sometimes the customer request to open mold but there is no image file, so we are only able to proofing samples (mould), using the sample size measurements for product structure, through sample data to measure the data to drawing, and then open mold, but by using data obtained from measurements usually may appear error, Only by using the sample to open the mold can we guarantee to reduce the number of mold modifications. In addition, the customer request product detailed image file open mode, in the process of open mould will often want to modify the mould, the sample mold at this time is a good way, as we write a report, the formal report does not allow any wrong character, first in the draft on paper, and then a formal written report, if any wrong character is rewritten in the report, Now the sample mold is equivalent to the paper of draft, and the formal report paper is equivalent to the production mold, with the silica gel sample mold can facilitate the modification of mold products. Finally, sample mould price is much lower than production mold, so if for modify the mold to mold scrap, sample mould due to the low cost for the company as a whole mould opening is also a way to reduce costs, if open mould by production mold directly if there is a damage to scrap that thed loss outweights the gain.

The difference between sample mold and large mold is:

1, the number of holes opened by the sample mold is less, the use of template is less, and the processing time is short, so the cost is relatively small, and the efficiency is high.

2, opening the sample mold can also bring some other benefits, such as even if the product structure has not been confirmed for the first time, it is more convenient to modify the mold, after modification can immediately confirm the proofing, so as to shorten the time.

3. Because of the low cost, opening the sample mold first can reduce the risk. If you directly open the large mold and cannot confirm the sample for the first time, there will be a lot of quality problems when using the modified mold to produce products. In this case, the mold will only be repaired more and more bad, which is not conducive to production. Therefore, the sample mold will be opened first for product confirmation. After no problem, the large mold will be opened again.

Open mold customization process:

1, by the customer to provide 2D/3D drawings or samples (when the samples are provided, the customized manufacturers copy the number of self-made 3D drawings);

2. Mold house master designs mold processing drawings according to 3D drawings;

3. The natural rubber factory takes the sample to make samples and gives the samples to the customer for confirmation;

4. After sample confirmation, open the large mold for small batch production, and confirm the product is no problem before mass production;
