ISO 9001, CE, CCC: What These Certifications Actually Mean for Your Equipment PurchaseWhen you're evaluating LSR injection molding machines from an overseas supplier, certification logos on a company website can start to blur together. ISO 9001, CE, CCC — they all sound reassuring, but they don't all mean the same thing, and they don't all matter for the same reasons. Understanding what each certification actually covers will help you ask better questions during due diligence and avoid assuming a certificate guarantees something it doesn't.

How we make the LSR half-mask respirator
This respirator is both high-efficiency and comfortable.
The LSR Half Mask Respirator is designed to protect you and be comfortable to wear. It uses a special process where two types of plastic are joined together. The result is a durable structure with a comfortable surface that fits closely to the face, reducing pressure and improving sealing performance.
What Is an LSR Half Mask Respirator?
This type of respirator is made through a combination of plastic injection and LSR overmolding. First, the plastic part of the mask is molded. Then it is placed into a silicone mold for a second injection on an LSR molding machine. During this process, the liquid silicone bonds tightly with the plastic surface, forming one complete piece without any need for glue or manual assembly. This makes the mask more stable, cleaner, and easier to produce in volume.
The Molding Process
The production of the LSR Half Mask Respirator follows three simple but precise steps:
Molding the Plastic Frame: Using materials such as PC or PA66 to give the mask its structure.
Secondary LSR Injection: The plastic part is fixed in the mold on an LSR molding machine, and liquid silicone is injected to create the soft sealing layer.
Curing and Finishing: After molding, the silicone cures and bonds firmly with the plastic. The finished mask is removed, inspected, and ready for testing.
LSR Half Mask Respirator & Traditional silicone mask process
Traditional silicone masks are made by first making the plastic parts and then the silicone parts, and then putting them together by hand. This takes more time and effort. Using an LSR moulding machine to combine both materials in one step saves time, is cheaper, and makes the product more consistent.
Customer Feedback and Improvement
When we first made samples, the mask would often slip off while people were wearing it. Our team of designers changed the design of the mould and tested several versions. After we made these improvements, the sample we sent abroad got great feedback.
The customer said the LSR Half Mask Respirator had an even material surface, smooth finishing, and a tight fit, making it comfortable to wear for long hours.
