Liquid Silicone Rubber Injection Molding Quotes: Are You Comparing the Same Scope?
Inhaltsübersicht
You send the same drawing to three suppliers and receive three different prices. One quote includes tooling and finished parts. Another lists a low unit price but leaves inspection and packaging unclear. The third includes several charges you did not expect.
Which offer gives you better value?
Before comparing prices for Spritzgießen von Flüssigsilikonkautschuk, check what each supplier has agreed to deliver. A useful comparison starts with the same requirements, not the lowest number.
Did Every Supplier Quote the Same Part Requirements?
The same drawing does not always lead to the same quotation assumptions. If your RFQ leaves details open, ask each supplier to identify what they used to calculate the price.
For liquid silicone rubber injection molding, give every supplier the same starting information:
Current drawings and matching 3D files.
Material grade, hardness, and color requirements.
Order quantity and estimated annual demand.
Critical dimensions and appearance requirements.
Intended use and any required testing.
If you have not selected a material grade, say so. Ask suppliers to name their proposed material rather than simply quote “silicone.”
Check drawing revisions, too. A price based on an earlier design is not directly comparable with one based on your latest requirements.
What Does the Tooling Price Actually Include?
A tooling price needs a clear description of the tool and the work covered by the payment.
When reviewing liquid silicone rubber injection molding quotes, ask suppliers to state the proposed cavity count, trial scope, sample quantity, and approval process. Do not assume two similar tooling prices represent the same production plan.
Clarify how changes will be handled. A correction needed to meet an agreed drawing should be distinguished from a design change requested after tooling begins. Record the responsibilities before placing the order.
Also confirm:
Who owns the mold.
Where it will be stored.
What maintenance is included.
Which conditions apply if you request its release.
These details belong in the commercial agreement, not only in later email discussions.

Which Operations Are Included in the Unit Price?
Ask a direct question: “What condition will the parts be in when you ship them?”
For liquid silicone rubber injection molding, the quoted price should identify which finishing and handling steps are included. Where applicable, check trimming, post-curing, cleaning, inspection, sorting, and packaging.
Avoid leaving “finished parts” undefined. Your assembly team may expect individually separated, inspected components, while the supplier’s quote may describe a different delivery condition.
Quantity assumptions also need attention. Compare prices at the same order volume and release schedule. An annual estimate of 100,000 pieces does not, by itself, tell the supplier whether you will buy one shipment or several smaller batches.
Ask for separate pricing where your purchasing schedule is still uncertain.
Are Inspection and Documentation Quoted to the Same Standard?
“Inspection included” is a starting point, not a complete inspection agreement.
Before approving a liquid silicone rubber injection molding quote, list the dimensions, appearance criteria, and functional checks that matter to your application. Ask the supplier to explain the proposed inspection scope and provide pricing for any additional requirements.
Separate the parts from the paperwork. Confirm whether the quotation includes material documentation, a first-article inspection report, batch records, or other requested files.
If you need third-party testing, define the test and responsibility for its cost. Do not assume a general reference to “quality documents” covers every report your customer requires.
The aim is straightforward: both sides should know what evidence will accompany the shipment and what criteria will determine acceptance.
What Will You Pay to Receive Parts Ready for Use?
Bring the full liquid silicone rubber injection molding quote into one comparison sheet.
Use three columns for every supplier: included, excluded, and awaiting confirmation. Cover tooling, parts, additional operations, inspection, packaging, and delivery.
Then separate first-order spending from repeat-order spending. Tooling and agreed development charges should remain visible rather than disappear inside a blended unit price.
Confirm the delivery terms, freight responsibilities, applicable taxes, quotation validity, and payment schedule. Check packaging against your receiving and assembly needs as well.
The strongest comparison is not the one with the fewest line items. It is the one that makes each supplier’s commitments clear enough for you to approve.
LSR Injection Molding RFQ & Quotation
Find answers about liquid silicone rubber injection molding quotations, RFQ requirements, tooling costs, unit-price differences, sample approval, and how to compare supplier offers before placing a production order.
What should I include in an RFQ for liquid silicone rubber injection molding?
Provide current drawings, 3D files, material requirements, quantities, critical acceptance criteria, and delivery expectations. Mark unresolved items clearly and ask suppliers to state their assumptions.
Why do suppliers quote different prices for the same silicone part?
Start by checking whether they quoted the same material, tooling configuration, quantities, finishing steps, inspection scope, and delivery terms. Request clarification before attributing the difference to quality or efficiency.
Does a lower unit price mean a lower total purchasing cost?
Not necessarily. Compare the complete agreed scope, including separately charged services and delivery costs. Review first-order and repeat-order totals separately.
Are mold changes and additional samples included in the tooling quote?
Check the written quotation. Agree on trial rounds, sample quantities, and the distinction between tool corrections and customer-requested design changes before ordering.
What should I confirm before accepting an LSR molding quote?
Confirm the drawing revision, material, tooling scope, unit-price inclusions, acceptance criteria, delivery schedule, payment terms, and quotation validity. Resolve open items in writing before issuing your purchase order.

Erfolgreich LSR-Formguss beginnt schon lange vor der ersten Produktionsserie.
Die Leistung des Kaltkanals, die Gestaltung der Entlüftungskanäle, der Schrumpfausgleich, die Vermeidung von Gratbildung, die Temperaturregelung und die Materialauswahl wirken alle zusammen. Schwächen in einem Bereich führen oft zu Problemen an anderer Stelle.
Wenn diese Faktoren bereits bei der Konstruktion der Form berücksichtigt werden, lässt sich der Produktionsablauf besser vorhersagen, die Ausschussquote sinkt und die Maßhaltigkeit verbessert sich über die gesamte Lebensdauer der Form hinweg.
