How to control the plastic mold quality

We work together with our customers to identify critical characteristics, helping us develop and customize a product plan to meet your requirements. Identifying key quality criteria in each project is an important element that we examine in great detail before your plastic mold goes into production. Material selection, dimensional tolerances, physical and mechanical properties, as well as end user expectations taken into consideration – numerous elements are factored in to achieve manufacturing excellence.

For over 10 years of experience with our creative approach to problem solving, we can manufacture complex components and assemblies economically, which still meet your strict requirements to achieve “zero defect” levels that is also we striving for. 

From materials incoming to finished product out-going, quality control process has been fully implemented to ensure lower re-work rate, lower wastage, higher efficiency, short delivery term. All mold steel or resin we used is strictly following customers’ quality requirements. We provide steel measurement inspection, first article inspection and full measurement reports.

Plastic Injection Molding Products

1. The composition of the injection mold
Although the structures of the molds vary due to different kinds of plastics and their performance, different shapes and structures of the plastic products as well as different types of injection machines, the basic structures of the molds are the same. The injection mold consists of the gating system, the temperature control system, the plastic molded part and the structural component. Among all the parts, the gating system and the molded part are in direct contact with plastics and change due to plastics and the plastic products, which are the most complex parts with greatest changes and are required to have good finishes and high accuracy.

The injection mold is composed of the moving die and the fixed die two parts; the moving die is installed on the moving die plate of the injection molding machine and the fixed die is installed on the fixed die plate of the injection molding machine. The moving die and the fixed die close to form the pouring system and the cavity in the injection molding process; when the mold is opened, the moving die and the fixed die separate so as to remove the plastic product. In order to reduce the tedious mold design and the manufacturing work, the injection mold mostly adopts the standard mold base.

2. Application fields
The injection mold is important technological equipment for manufacturing various industrial products. With the rapid development of plastic industry, the plastic injection molding products are widely used for industrial sectors such as aviation, aerospace, electronics, machinery, shipping and automobiles.

3. Features of plastic injection molding products 
(1) Being lightweight
It is very common to see plastic products in our lives and they are very light and not easy to be corroded. Because the plastic molding products are very light, people adopt plastics for a lot of food packaging. Plastic products are light and convenient, which brings lots of benefit to people.

(2) Good impact resistance
We often see some soft or hard plastic products in our lives and both of them have very good impact resistance, especially the soft plastic products. Stamping on the plastic products or using something to press the plastic products won’t cause any harm to them. Plastic basins and plastic bags are very common to be seen in our daily life.

(3) Good transparency and wear resistance
Speaking of better transparency, plastic bags and food packaging are the first things i think of. They not only have good impact resistance and transparency, but also have beautiful appearance.  Good transparency makes observation of products easy for customers.

(4) Being soluble in solvents
Some plastic products are easy to be melted. If the manufacturers are not satisfied with the finished plastic products, the finished plastic products can be melted and produced again. However, we need to properly recycle the waste plastic products.

Injection Molded Plastic Parts

Our position is quite unique in the consulting business. We combine a strong plastic molded parts and mold technical expertise with strong business savvy. For the purposes of this review, I will concentrate on the plastic injection molds and injectioi molding Technical and Market Research and Analysis portion of our business.

Our Background
HPT was created in 1979 as a direct result of a joint venture between Clopay and a Belgian holding company. HPT was then formed to do the technical marketing for the joint venture. Originally based n Cincinnati, we moved the business to Florida in 1992 when we began our first consulting contract. This was a yearlong project to do a full market study on the hygiene markets in Latin America.

The end result of the Latin American study was a recommendation for our client on what products to make, how to distribute and price them, and who to sell them to. (The company was Ace Films and the product was diaper-backing sheet.) Our study included a full analysis of the competition and the major trends. HPT was then asked to handle marketing for this client in Central and South America. (We then did a similar study for a Korean manufacturer 1988 and 1989. The Korean study was U.S. based.)

Previous and Current Work
Five years ago HPT began industry consulting and lead application analysis for new technologies. All our contracts are covered by Confidential Nondisclosure agreements, but I can tell you the general areas of work:
·Medical Disposables
·Absorbent Plastic molding Parts
·Specialty Resins
·Biodegradable Resins
·Breathable Films and Resins
·Home Health Care
·The Senior Care Market
·Pet Injection molding Products
·Wound-care
·Specialty Films


ST Plastics. is known in the Nonwovens and Films and Absorbent Injection Molded Plastic Parts industry as an innovative marketer of raw materials to the medical and hygienic markets, the graphic arts industry, and packaging. Our consulting business has been very specialized and confidential and thus less well known.
In our position as a large seller of films we have regular contact with resin suppliers and other plastic converters. This puts us in an excellent position to interview and visit producers and consumers of products we are researching. We have an excellent network of manufacturers of plastic and web products, and this gives us good ?hands-on? and field experience in the areas that we research. In the medical field we both consult and supply raw materials to this industry. We attend many technical conferences and trade shows to broaden our expertise and exposure.

The type of work we do:

1.Market research- who is buying what and why. This work is done on an industrial level. Most of our work is field interviews and visits. Often we will start with a multi-client report prepared by someone else and then dive much deeper into the specific areas of interest to the client.
2.Field Intelligence – We can visit factories and shows and utilize our existing contacts in the industry and hasten the information gathering process. We will, for example, directly contact hospitals, medical device manufacturers, vendors, technical experts, and processors. We gather samples, technical data and marketing literature and pricing.
3.Act as an ?Enigma? – HPT will gather samples, test data, make inquiries of potential suppliers or acquisition targets, attend conferences, meet prospective vendors, converters, or consultants shielding unwanted exposure from the client.
4. Prototyping – Using our existing contacts in the fabrication arena, we can facilitate the prototyping process
5.Full team members – we participate in the basic ideation sessions, the focus group work, the planning sessions, and we consider ourselves major contributors to the team effort. Our experience in plastics, coatings, the medical fields, acquisitions, profitability, and industrial marketing make our input in planning and execution valuable. We can bring insight into the analysis that my not exist internally.

Plastic Injection molding outsourcing to China

Outsourcing plastic injection molds to mold manufacturer China companies have become very commonplace, but it is not always as successful as hoped for. The strategic planning of your offshore outsourcing will make all the difference in your attempt to gain new business and develop new products. When you outsourcing your plastic molds to China mold companies you may need to travel to China any times, maybe 1-2 times per year, if you have lots of projects that make from plastic mold company in China, then you may need to do the business traveling 5 time per year or maybe more.

Here are some of the successful plans global companies are using that really work. By utilizing these ideas, as they fit your unique needs, you can develop a strategy to not only survive in today’s extremely competitive international market, but thrive.

Those companies that are flexible and willing to adapt, often discover that entering into the global market reveals new opportunities for growth and profit. Global technology is a reality that can be used to your advantage.

Combine domestic and global technology to win contracts

Very often, plastic injection molding contracts are presented as a “package.” This can vary in it’s size and structure, but for our purposes, let’s use the following example:

Your molding or plastic mold company has an opportunity to bid on a new product that requires the building of eight plastic injection molds. You already know that other companies are bidding on the job, and they use offshore outsourcing to lower their costs.

Because you have wisely found several reliable, high quality offshore suppliers for injection molds, you are able to combine your resources to effectively quote the job. You can win in the global market by being flexible and using proven strategies.

Finding such an offshore source can be time-consuming and expensive, if you take it up on your own. The companies listed on this site are all known for their integrity, high-quality and pricing.

A very effective strategy

After a close examination of each job and how it fits in with the overall package, you determine that you will break up the eight molds as follows:

  • Keep the complicated work in-house
  • Send the simple, less risky work offshore
  • Split up the rest by deadline and level of expertise required. Send the easy part of the remaining difficult work offshore, such as simple cores and cavities, and manufacture the difficult parts in-house.

How does this benefit your company?

  • Spreads your risk out
  • You develop a working relationship with your offshore suppliers and work out the communication bugs and technical bugs.
  • You save approximately 350%
  • You can get more work done without hiring additional staff that you probably couldn’t find anyway!
