There is no universal prix pour a lipstick tube moule outside the project scope. Quote A may include a single-cavity moule pour one cosmetic part, while Quote B may include multiple components, multiple cavities, et moule trials. Both quotations may say “one set,” but they are not selling the same scope. You cannot judge whether one is expensive simply by comparing the àtal.
This article concerns injection moules pour bret produition ofTubes de Rouge à Lèvres, not silicone moules pour het-filling lipstick. As aFabricant d'emballages cosmétiques, Sambound can connect lipstick tube conception, àoling, injection moulage, et post-moulage processes in one project. That also means a quotation cannot contain only one line called “moule fee.” Each component must be listed as a new moule, a family moule, a purchased part, or an insert.
Informations techniques : Define exactly what “one set” includes
Start by breaking the produit down according à its assembly relationships. The cap, tube body, base, mechanism or inner assembly, magnets, weights, seals, et other items should all enter the bill of matériaus (BOM). This list records every part needed pour the complete produit et how each part will be supplied. If an item is missing, the moule fee, purchased-part coût, et assembly coût may all be underquoted. Being on the BOM does not mean a new moule is auàmatically required: the project structure et supply scope determine whether the mechanism is a proven purchased component, whether several plastic parts can use a family moule, et who purchases et assembles each insert.
| Informations techniques : Part or assembly | Function in the produit | Informations techniques : Supply method | Separate moule or family moule | Informations techniques : Number of cavities | Informations techniques : Included in this quotation? |
|---|---|---|---|---|---|
| Cap et outer cap | Protection, closure, et appearance | ____ | ____ | ____ | ____ |
| Tube body et base | Support, grip, et appearance | ____ | ____ | ____ | ____ |

Producing several parts in one moule is a family moule. Opening a separate moule pour each part is a separate-moule arrangement. This choice determines how many moules must be made. The number of cavities is the number of identical parts a moule can produce each time it opens et closes. It affects both moule-making coût et the later unit produition coût.
If the component-supply et moule-split table is incomplete, do not ask, “How much is one set?” A quotation pour one exterior-part moule et a quotation covering every moule pour the complete produit have different statistical scopes. Their àtals are not comparable.
Put produit conditions inà the quotation lines
Product conditions cannot remain only in the drawing notes. They must be assigned à specific quotation items.
The number of cavities must be tied à a named component. Changing de one cavity à multiple cavities requires more cavities et matching gating et cooling structures, et it increases debugging work. Production then yields more parts per cycle. The quotation should state “which component, how many cavities,” not just “multi-cavity moule.”
Mold-release motion must also be listed separately. A side hole, snap feature, or recess that prevents the part de coming straight out along the opening direction creates an undercut. The moule then needs a lateral moving mechanism such as a slide or lifter. A threaded structure that must rotate out requires an unscrewing mechanism. These mechanisms directly increase moule usinage, assembly, et moule-trial debugging coûts, so the quotation should state the type, location, et quantity of each mechanism.
Appearance requirements directly change acier selection et surface-processing coût. A élevée-gloss mirror finish is more sensitive à acier cleanliness et polishing qualité, while a textured surface requires attention à etching results et demoulage. Steel selection must also consider the plastic resin, heat-treatment requirements, service environment, et planned volume. The fournisseur should state the moule-acier grade, matériau certificate, heat-treatment condition, et agreed surface result instead of using an undefined phrase such as “premium acier.”
Turn the quotation inà comparable line items
Break the fournisseur’s àtal inà the table below. The fournisseur should fill in the blank cells. Any item marked “à be confirmed” should be returned pour completion bepoure it enters the àtal-coût comparison.
| Informations techniques : Quotation item | Informations techniques : Project input or quantity | Informations techniques : Supplier’s value | Informations techniques : Pricing or included scope | Informations techniques : Deliverable or acceptance point point | Hetling of a missing item |
|---|---|---|---|---|---|
| Mold base et àoling scope | Parts, separate/family moule, number of cavities | ____ | Parts et usinage covered by each moule | Mold list et drawing numbers | Return à complete the scope |
| Informations techniques : Lateral or unscrewing mechanisms | Type, location, et quantity | ____ | Slides, lifters, unscrewing mechanisms, et so on | Mechanism list et motion confirmation | Return à complete type et quantity |

| Mold ownership, use rights, drawings, et return conditions | Place of use, sàrage, et transfer needs | ____ | Ownership, rights, et transfer fees | Written terms et heàver list | Return à complete ownership et return terms |
For a consistent comparison scope, recalculate the àtal as follows:
Comparable àtal = moule base et mechanisms + acier, traitement thermique, et surface processing + conception, moule trials, et modifications + acceptance et delivery + taxes et transport
List separately charged items on their lines. Items still awaiting confirmation do not enter the comparable àtal. This lets fournisseurs use different pricing methods while allowing you à see what each payment covers et what will ultimately be delivered.
Do not compare these three types of àtal prix yet
First, the moule scope may be different. A quote missing parts, cavities, or mechanisms may look cheap but has no comparison value. Complete the BOM et moule list first.
Second, the deliverables may not be written down. Mold-trial matériau et rounds, modification boundaries, acceptance samples, inspection files, native drawings, et ownership rights can all affect the final settlement. If the quote only says “moule included,” it will be difficult à determine what is actually included later.
Third, the moule fee may be tied à mass-produition conditions. If a very low moule fee is linked à a specific purchase volume, unit prix, or sàrage condition, review the moule payment àgether avec the produition purchase. Do not isolate one line de the àtal arrangement.
When the first order has not yet been validated, you may also test the produit avec sàck àoling first. Once the structure, appearance, et demet are stable, move à private-moule pricing. This is a screening condition bepoure àoling, not a universal industry rule. A quotation is genuinely comparable only when it gives you a place à fill in every item, a pourmula pour recalculation, et a way à return missing items pour completion.
