The tolerances used by Abatek for compression molded silicone have been established by an ISO standard.

Standards monitoring is a free service designed for you who wish to be alerted of changes to iso 3302-1 new editions of the standards required in your iso 3302-1. Also the keypad is not secured to the PCB first so all components must be aligned together. Search all products by. Ideally, all keypad parts would measure perfectly at iso 3302-1 dimension.
Undercuts are difficult to tool and production parts are more likely to tear during removal from mold.
Tolerance class M3 middle mm. Deburring Deburring takes place after 3302-1 pressing or injection moulding production stage. As with all custom iso 3302-1, testing should be performed to assure the sealing performance of the design.
Because of the variable shrink rate, Abatek is limited to iso 3302-1 tightly part dimensions can be held. Abatek will review each undercut wrap design, taking into account material hardness, shape, keypad base thickness and other factors before confirming feasibility. DIN Part 5 specifies the permitted tolerances for plates iso 3302-1 plate-based articles.
You need izo log in before adding standards to the monitoring service.
The pressure applied iso 3302-1 the screws can help seal the keypad against the housing. XX This is the Mercedes Benz supply specification for O-rings and similar sealing rings manufactured from elastomer. Click to learn more.
Most applications can benefit from using the silicone keypad to seal with the housing and protect the PCB from the environment. The relevant tests are also stipulated in the standard. There are two iso 3302-1 ways of removing burrs:. Monitoring Standards monitoring is a free service designed for you who wish to be alerted iso 3302-1 changes to or new editions of the standards required iiso your work.
The tool 33021- to easily guide and push the spigot through without damage. If iso 3302-1 key-cap is fixed to the keypad, both the keypad and the plastic cap may be forced out of position causing poor actuation iso 3302-1 or even web failure.

Iso 3302-1 website is best viewed with browser version of up to Microsoft Internet Explorer 8 iso 3302-1 Firefox 3. This service is not available if you are a URL user iso 3302-1 you do not log in with an email address. With very large keypads, some dimensions will have shrink variance and wider tolerances – which coud cause fitment issues. The tolerances per ISO for compression molded silicone becomes wider as the dimension becomes large. Start Webshop Product catalog Product presentation.
When injecting into a mould, the satellite channels and the burr created between the halves of the tool must be removed. Please download Chrome or Firefox or view our browser tips. Only the end is initially pushed through the PCB.
When the tool is removed, the hole acts like an undercut feature – further retaining the keypad. This standard works with application keys, with the key describing the contact medium and the material. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. As the burr is thinner than the actual material, it is very brittle and iso 3302-1 breaks off much more easily than the component with its much greater mass of material.

A web subscription provides an easy and secure access to standards, and you iso 3302-1 guaranteed to always have the latest edition. First the silicone material will stretch and deflect in tight assemblies Second with good design, very precise iso 3302-1 of the keypad is not required.
The difference between the two is dependant on if one half or both mold halves iso 3302-1 used to create the dimensions. Customers who bought this product also bought BS EN
