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.

Details about the LSR injection molding process
In last artical, we learn that how the liquid silicone injection molding working, and now we try to explain while mold production and part production.
Mold production
When an order is placed, TYM will design an LSR molding tool. Due to the flexible feture of LSR, parts are manually removed from the mold, and thus, ejector pins are not built into the mold design. Like a standard Protomold aluminum tool, an LSR molding tool is fabricated using a combination of CNC milling and CNC electrical-discharge machining to create a high-temperature aluminum tool built to withstand the LSR molding process. After milling, the tool is polished by hand to customer specifications, others may be available by request.
Part production
The finished tool loaded into an advanced LSR-specific injection-molding press that is precision geared for accurate control of shot size to produce the most consistent liquid silicone rubber parts. LSR molding shares many similarities with conventional injection molding, but there are a few notable differences. Unlike thermoplastic resin, which is melted before injection, LSR is a two-part thermoset compound that is chilled before being injected into a heated mold and ultimately cured into a final part. Note that Protomold uses an automated meter mixing pump to assure the exact combination of the two-part compound; nothing is hand mixed. Since LSR is a thermosetting polymer, its molded state is permanent .
