Trying to locate the best rubber cork manufacturer will require taking a close look at several factors. You want a dependable company that can keep you supplied with the right quantity. Quality also has to be a huge consideration to ensure you are buying a product that lasts under all conditions. Keep reading to learn the seven criteria you should look at to determine the best manufacturer of stoppers for your needs.
1 Fast Order Fulfillment
The level of inventory of rubber corks available is critical when you have urgent needs to get the product right away. You should always discuss your average stopper order fulfillment needs and see if these can be met with available inventory, or whether you’ll have to place orders well in advance of when you will have them delivered. Will your chosen manufacturer be able to deliver large orders in a reasonable amount of time? Freely discuss their manufacturing methods and abilities. You want to feel comfortable they can handle large orders before you choose them and feel let down at slow progress. Find out what their capacity is and determine if it suits your order requirements.
2 Designed for a Variety of Uses
A Manufacturer that specializes in offering well-constructed rubber corks should offer them for all types of uses. The design needs to offer a snug fit that allows a complete absence of leaks. Not all containers using stoppers hold caustic chemicals, but it might contain items that require a seal to stay fresh and good to use. A few of the uses for rubber corks are containers that hold:
- Laboratory chemicals and powders
- Medical samples and testing chemicals
- Spices and extracts
- Homeopathic medicines and tinctures
- Powdered minerals
- Soil or water samples
- Aromatherapy oils
3 Large Variety of Sizes
Measuring a rubber cork for a perfect fit is something a manufacturer should be able to do quickly and tell you if they provide the right size to seal your container. The smallest end of the stopper goes into the top of the container first and should comfortably slide down. The taper should move outwards and allow for the stopper to be forced into place with ease by pushing down.
Choose a rubber cork manufacturer offering numerous sizes in their inventory. You may only need one particular size at the moment, but what if you decide to add other products or conduct other tests that require a different size container? You’ll have to change the rubber cork size as well. You may be forced to change container sizes by a switch made with your containment provider, which will automatically require a new size rubber cork.
4 Excellent Selection of Materials
Not every rubber stopper works for each application. It’s nice to find a manufacturer that creates rubber corks out of a variety of rubber materials. Many people are familiar with the all-black EPDM rubber corks, but you can also find them made with silicone, neoprene, and pure gum. Each should be made with a solid feel that lets you know it can handle the job. Ask to purchase samples before making your final choice.
Air circulation can be a factor when stoppering some chemicals. Is the rubber cork manufacturer you are considering able to create stoppers with holes that allow the chemicals to breathe? You want to feel confident that every aspect of the needs of your business is considered in the design and creation of specific rubber corks. Make sure the rubber corks you are considering are made with the right design for the job ahead.
5 Temperature and Chemical Resistance
Only stoppers made of quality rubber and sound design will provide many years of unblemished service. You don’t want them to begin cracking and leaking after a few months of use. Ask to see the results of any high-performance tests that have been done on the cork material you choose. A great manufacturer will be happy to provide you with this critical information.
The design of stoppers made of rubber should be able to keep chemicals contained safely in laboratory and testing environments, even under harsh temperature conditions. Quality stoppers will work effectively from temperatures in the range of 160F or 70C up to 550F or 28C, which are the parameters of most temperature-sensitive testing situations. Anything less could fail at critical moments and compromise your activity or results.
6 Ability to Order in Bulk or Small Amounts
Most manufacturers of rubber corks will be happy to see large bulk orders cross their desk. The critical questions to ask are how quickly can these larger orders be filled, and will you save any money on bulk purchases? A stopper manufacturer receiving consistent bulk orders should be willing to give you special pricing for buying in large quantities. It should be the beginning of a good working relationship.
You also should be concerned about being penalized for ordering small amounts of stoppers. It could be necessary to purchase a smaller amount of stoppers that are of a different size than your normal order. You don’t want to find out at the last minute that there is a minimum amount that has to be ordered to get the few you need. You’ll end up with too much extra sitting around your storage areas.
