What is Injection Mold Manufacturing?
Injection mold manufacturing is a precision process that converts materials such as tool steel, pre-hardened steel, and aluminum alloys into customized molds through specialized machining and fabrication techniques. At its core, the goal is to leverage the unique properties of these materials to create durable, repeatable tools capable of producing high-precision plastic parts. This allows product designers to not only validate prototypes but also scale to mass production at a million-unit scale.
As the foundational step of the injection molding process, mold fabrication is an indispensable step in plastic part manufacturing, bridging design concepts to tangible, high-volume outputs.

Many clients worldwide have had various types of molds manufactured at First Mold
“As a product engineer, I needed a partner who could handle both low-volume prototype molds and high-volume production tooling. First Mold’s team delivered a multi-cavity P20 steel mold that cut our development time by 30%. Their expertise in thin-wall molding for our IoT devices was a game-changer – no more sink marks or warping issues. Now, we’re scaling to 500k units with zero defects.”
Alex Johnson
Ingénieur produit senior
“Managing automotive projects requires molds that survive 500k+ cycles. First Mold’s hardened S136 steel molds for our EV battery housings exceeded expectations. They even suggested a conformal cooling design that reduced cycle time by 15%. Plus, their ISO-compliant documentation sped up our supplier audits.”

Workflow of Mold Making Service
At First Mold, our systematic mold manufacturing workflow ensures precision-engineered solutions, typically structured into six key phases:
1. Product Analysis & Mold Design
Based on the product’s structure, material, and customer requirements, First Mold conduct feasibility analysis and manufacturing feasibility assessment (MFA). Our mold designers then create detailed 3D CAD models and technical 2D engineering blueprints for all mold components.
2. Mold Material Selection
We select materials (e.g., H13, S136, P20 steel, aluminum alloys, beryllium copper) based on production volume, purpose, and budget. Heat treatment requirements for the mold are also pre-evaluated to enhance durability and longevity.
3. Precision Mold Machining
Components such as cavities and cores undergo rough cutting, high-precision milling, and surface treatment. Processes include CNC milling, electrical discharge machining (EDM), and precision wire-cutting technology.
4. Mold Assembly and Debugging
We assemble mold parts with strict attention to tolerance control. Mold fitting tests and functional tests are performed to prevent defects during plastic injection molding production.
5. Trial Molding and Optimization
Trial runs are conducted on First Mold’s high-precision injection molding machines. Parameters are recorded, defects are analyzed, and the mold is optimized to ensure seamless production and part consistency.
6. Mold Delivery and Acceptance
We determine whether to ship the high-quality mold to the customer based on their decision to proceed with mass production at First Mold or their own facility.
Injection Mold Solutions Applications
The ultimate goal of the injection mold making service is the production of injection-molded parts. The molds produced can either be used by the clients for their own injection molding production or entrusted to manufacturers for injection molding production.
These two sets of images are molds used in the consumer goods industry and medical molds in their final application during production.

What is the typical turnaround time for a custom injection mold project?
Notre délai de livraison des moules commence à partir du moment où vous confirmez la commande et où nous commençons la conception du moule, et il s'étend jusqu'à la phase du premier essai.
Pour l'outillage rapide, nous achevons généralement le processus en 7 jours, tandis que pour les moules de production, le délai s'étend généralement de 30 à 45 jours. Étant donné que les moules de production nécessitent plus de temps, notre équipe maintiendra une communication étroite avec vous pour s'assurer que vos exigences sont satisfaites.
Avant le premier essai officiel, nous effectuons des essais internes. En outre, nous procéderons à deux ou trois essais supplémentaires afin d'identifier et d'éliminer efficacement les défauts potentiels de moulage par injection qui pourraient survenir au cours de la production.
What if modifications are needed after injection mold manufacturing has started
We understand that changes may be required even after production begins our team will promptly assess the requested modifications and discuss the impact on cost and schedule then implement controlled adjustments to ensure the final mold maintains its precision and quality while minimizing disruptions to your project timeline
