![How to Verify Whether a Supplier's]()
How to Verify Whether a Supplier's "Parts Per Hour" Claim Includes Color or Mold Changeover TimeWhen comparing liquid silicone rubber (LSR) injection molding machines, almost every supplier quote includes a headline number: parts per hour, or cycles per hour. It looks like the easiest number to compare — until you realize it rarely means the same thing from one supplier to the next.

Common Failure Modes in In-Mold Assembly (IMA) on Double-Color and Double-Material LSR Machines
In-mold assembly — molding a silicone component directly onto or around a second material within a single cycle — is one of the strongest arguments for double-color and double-material LSR machines. It eliminates a secondary bonding or assembly step, reduces labor, and improves consistency versus post-mold assembly. On paper, it sounds like a straightforward efficiency gain.

Cold Runner Clogging in LSR Injection Molding: A Practical Troubleshooting Guide
Cold runner systems are one of the main reasons manufacturers choose liquid silicone rubber (LSR) injection molding over conventional runner designs — no gate vestige, no flash to trim, and lower material waste. But when a cold runner starts to clog, that advantage disappears fast: production stops, scrap rates climb, and every hour of downtime costs real money.

Pure Electric Servo Feeding System vs. Traditional Pneumatic Feeding: Which One Actually Saves You Money?If you run an LSR (Liquid Silicone Rubber) injection molding line, the feeding system is easy to overlook — until it starts costing you scrap rate, downtime, and inconsistent shot weights. Two technologies dominate the market today: pneumatic (air-driven) feeding systems and pure electric servo feeding systems. Here's an honest, practical comparison to help you decide which fits your production line.

How to Choose an LSR OEM Manufacturing Partner: A Buyer's ChecklistOutsourcing liquid silicone rubber production is as much a relationship decision as a technical one. A supplier can look strong on paper — certificates, equipment lists, a polished website — and still fall short once your product hits real production volume. Here's a practical checklist for evaluating an LSR OEM partner before you commit tooling and inventory to them.

Liquid Silicone Rubber Injection Molding---History Introduction
Liquid Silicone Rubber Injection Molding (LSR injection molding) has been widely used in many markets due to its ability to produce intricate elastomeric components with relatively short cycle times.
The automotive industry uses silicone's high degradation temperatures for engine sealing and medical components markets rely on its biological inertness. Liquid Silicone Rubber (LSR) can be processed using slightly modified thermoplastic molding equipment, making them easy to integrate into existing business structures and facilities. Also, an increase in use has driven down the raw material cost of LSRs as to make them more competitive with historically less expensive thermoplastic elastomers, thus extending their use into new markets in recent years. An increase in specialized auxiliary equipment such as demolding devices will further facilitate LSR push to the mainstream of polymer manufacturing.
Among the whole silicone material, Liquid Silicone Rubber (LSR) has a relatively short history.
Developed during the late 1970s, LSR two component systems have quickly increased in popularity over the past 30 years due to their
advantages over Gum Silicone Rubbers. Not only are faster cycle times and flashless molding possible, but all secondary equipment is contained near the molding press and there is no need to mill or process the material in any way prior to use. Also , LSR is popular due to its ability to compete with typical thermoplastic elastomers which allowing for minimal initial capital investment.
In next part, we will try to write something about the material and the process about the liquid silicone rubber molding, kindly contact for more details .
